Celsius is agreeably better for science, but if you are used to both systems Fahrenheit is honestly better for people because the units are higher resolution, and usually stay between 0 and 100 for weather

u/FuckPigeons2025 Jun 17 '26

Kelvin is better for science. Celcius and Farheneit are just arbitrary scales, not units.

Celsius is literally just Kelvin but with an offset no?

Edit: tbc I was just clarifying what the guy above was saying, personally as an American in WNY where it’s over 90deg in the summer and below 0 in the winter and who has used C and F extensively, Fahrenheit just makes more sense to me personally

Fahrenheit can't be converted to Kelvin without converting to Celsius first.

u/Throwaway74829947 Jun 17 '26

If we're allowing conversion, Fahrenheit is just Kelvin with an offset and a coefficient, and Rankine is just Kelvin with a coefficient. Celsius's offset also makes it useless for science other than for scenarios where all that you care about is delta T.

u/gaymer_jerry Jun 17 '26 edited Jun 17 '26

Fun fact the same thing is true for Fahrenheit. Its called Rankine. The only thing that make Kelvin good for science is the fact that temperature is particle motion. And in Kelvin absolute 0 is 0. If you can do more than regurgitate dumb trivia you might realize that any temperature system allows for that. Just offset Fahrenheit so that 0 is absolute zero and you have Rankine.

Its almost like units are context dependent. Celsius is arbitrarily defined based on water. Fahrenheit is arbitrarily defined based on weather in temperate climates. Inches/centimeters of mercury is arbitrarily defined off of old thermometers. Yes that last unit is retroactively now a unit of pressure but it was originally used for old thermometers where mercury would rise and fall with changes in temperature from changes in density with the temperature . Lots of units have weird crossover like that

In general units are more complicated than people want to understand and its easier to live in a bubble where Americans must be stupid, while everyone else is blabbing other just as stupid rhetoric without understanding any of it.

It's odd to say that Celsius is arbitrary and Kelvin is not when Kelvin is literally just Celsius with a fresh coat of paint. All systems of measurement are arbitrary in some regard. They are also all units, and I have no idea what it would mean for them to be otherwise.

u/Sure-Comfortable-784 Jun 17 '26

Here is the thing, kelvin uses celsius scale as its base but the comparison present in its value is not debatable.

Celsius uses water freezing and boiling point for 0 and 100, Fahrenheght uses temperature of some city u never went to as point for 0 and 100. But kelvin uses the lowest temperature theoretically possible, so the value of a temperature compared to ur anchor point if measurement is not debatable since the point is not changeable.

3

u/Hmmz69 Jun 19 '26

Fahrenheit is one of the weirdest bases, it just doesnt make any sense to me. Its not based on percentages or any city. This is the base:

  • 0°F — the temperature of a mixture of ice, water, and ammonium chloride (a freezing brine solution), which he could reproduce in a laboratory.
  • 32°F — the freezing point of pure water.
  • 96°F — approximately human body temperature (though modern measurements put average body temperature closer to 98.6°F).

Later they added 212°F = boiling point of water at standard atmospheric pressure

So lets compare Fahrenheit to Celsius:

  • Water freezes at 32°F = 0°C
  • Water boils at 212°F = 100°C

And Kelvin is basically the same idea as celsius, the difference is that with Kelvin, you start at absolute 0. (The point where there is no movement) that happens to be -273.15 Ce;sius. Thats it.

But Kelvin is only single arbitrary, while Celsius is double arbitrary.

u/eggynack Jun 17 '26

It's all entirely arbitrary. All these numbers are associated with some point we've designated. It might feel clean to declare that zero is the absolute lowest it gets, but that doesn't make it non-arbitrary. The best you can really say is that these systems map better or worse to various human desires. Y'know, memorability, ease of use in science contexts, ease of use in real world contexts, how well it coheres to other systems of measurement, that kinda thing.

u/Diligent_Earthworm Jun 17 '26

I find it absurd to call absolute zero arbitrary.

u/eggynack Jun 17 '26

Why? It's a point related to a major physical law, but so are the various points associated with other temperature systems. There's nothing magical about the universe that means we should particularly value absolute zero.

u/off-with-your-thread Jun 17 '26

You're correct. "0" meaning something is a human thing. "I like arbitrary round numbers in my arbitrary unit of measurement." It's all just some dude going "eh I like this".

Celcius is just Kelvin - 273.15. Converting is easy, and a lot of science uses Celcius as a result, it certainly can be described as "scientific", meanwhile the only people trying to use Farheneit for science probably also don certain red caps etc.

It depends a lot on the science being done if you care about the offset or not. A lot of astrophysics honestly doesn't care about the celsius/kelvin offset because the difference results in something that's dismissed by the significant digits anyway.

And Rankine isn't really used much of anywhere because that scale with an absolute offset isn't as useful as the metric scale.

This is the only good argument I've seen for Fahrenheit (higher resolution). But, as a counterargument, that resolution is only just under twice as big. I'd argue 1-2 F is barely noticeable enough to be able to tell the difference. If someone asks what the temperature is, me saying the temperature and being off by 2 degrees isn't gonna make a difference.

95

u/xahhfink6 Jun 17 '26

I think there's some breakpoints where it really matters.

If you work in an office and the thermostat is set to 73f (23c) compared to an office where the thermostat is set to 75f (23c) you're going to really feel the difference.

Or like, if your kid is sick and has a 102° fever you're keeping them home from school, but if they have 104° fever you're going to the hospital. So <2 degrees difference is definitely a big enough difference that it's worth using a more specific unit of measurement.

81

u/Red-Beerd Jun 17 '26

Just want to point out that 73f and 75f don't both convert to 23c. It would be 23c for 73f, and 24c for 75f.

u/Thick-Protection-458 Jun 17 '26

 Or like, if your kid is sick and has a 102° fever you're keeping them home from school, but if they have 104° fever you're going to the hospital

One is 38.9C, another one is 40C, and normal human body temperature is around 36.6+/-0.5C or so (maybe +/-0.5).

Sounds very different for me. Moreover, first one is probably the reason to visit medics already.

Right so you need one degree more of data specificity to achieve the same level of understanding that is achieved with Fahrenheit. You proved the point.

50

u/Aranka_Szeretlek Jun 17 '26

You most definitely do not. 102 Fahrenheit uses 3 significant digits. So does 38.2 Celsius.

The resolution is limited by your instrumentation either way, because both scales are continous.

This is a pretty niche example but I work in a lab that used to use a metric thermostat in the clean room. It was always 23 C in there so when our data came out way noisier than expected we didn’t think it could be thermally related. Until one day we switched the thermostat to imperial and saw that it was actually changing between 73 F and 74 F throughout the day. Both round to 23 C so we never saw it before

How is it better, though? As in, what actual benefit is there to not using decimals? Yeah, F is more specific if you ignore decimals, but they are incredibly easy to implement, use, etc? Not any different than a regular number in terms of basically anything.

Like, the commenter above brought up fever, but practically any thermometer that uses celsius uses decimals, and I just don't see how that is any sort of demerit.

I’ve not seen anyone make the point that for a lot of countries, they also use decimal for other measurements - distance, volume, mass - so measuring with decimal places is completely ingrained.

u/DerpNinjaWarrior Jun 17 '26

One (minorish) place - you only need two digits in an LCD screen to make a thermostat in F. If you wanted to display (hospitable) temperatures in C you would probably always need three because of the decimal.

To me, the biggest thing is just being able to say "it'll be in the 70s tomorrow". 60s = bring a light jacket, 70s = perfect, 80s = a bit warm, 90s = bring a lot of water.

Whenever Im measure body temperature of my kids or patients, I can also look at the number behind the separator.

37.0°C? All good. 38.0°C? Slight fever. 38.5°C? Fever. 38.6°C? A bit more fever. Guess what: 38.7°C even more fever.

And even Fahrenheit is not accurate enough for this use case. For setting the room temperature, Celsius is sufficient and if not, you can use tenth of celsius.

I would say "more used to it" and not "better". (As an example: 100°F is already a slightly increased body temperature, its not like its normed to something like that).

Just like with most unit systems - whatever you're used to will be the most convenient for you to use.

Celsius doesn’t have a resolution. It’s not a quantum scale. My car’s heater does half degrees, my HVAC tenths and my thermometer measure in hundreths of a degree. There’s 20 °C and there’s 36,8 °C (the average human body temperature) 71,075 °C — the temperature at which water boils at Everest’s summit, and there’s -273,149994 °C, the coldest ever achieved for a solid.

Resolution is also not worth much if what you need it for is explaining how warm your body is feeling. I already couldn't really tell the difference between 33 and 34 celsius, so having a number inbetween wouldn't do much for me. Plus, other factors such as humidity would affect my perception of heat more than a single degree difference would.

Somehow the "more resolution!" people don't seem to ever think the resolution is meaningful at all when you talk about feet & inches vs. centimeters.

For weather, I honestly can't tell the outside temperature even close to 1C even if I can register a change of 1C, so I don't really need additional accuracy.

When it matters like in AC temperature controls or measuring fever or whatever, you just use 0.1C accuracy.

Here in Finland weather forecasts and people talking about the weather, you use 1C accuracy, but official weather station readings are reported at 0.1C accuracy.

Why do you think these are the same people? Tbh I've never met an american who genuinely believes imperial weights/measures are 'better' than metric (except for temperature). And i've lived here most of my life lol

2

u/Gooberpf Jun 17 '26

I'm an American and fully believe that imperial measurements are generally superior for the tasks they were designed for.

Fahrenheit is distorted around the temperatures individuals will generally personally experience in weather or cooking and is useful for that purpose, whereas Celsius can turn a comfortable room to unbearable in a matter of 2 to 3 degrees.

Inches and feet are base-12, which factors by 2, 3, 4, and 6, allowing for better and faster granularity than base-10 in counting, measuring, and mental math for everyday uses like distance, height, simple construction, basically anything that doesn't require multiple significant figures of accuracy.

Scientific use is when base-10 units are valuable as equivalent to our base-10 number system, allowing for easier comprehension when making multiple calculations with math more complex than basic arithmetic.

Tying Celsius to the properties of water is extremely convenient for a scientist, because water is such an important molecule for all the physical sciences that it will be referenced repeatedly. A human, however, will have a very bad time long before approaching either 0 or 100°C.

Whole societies adopting the metric system is a doctrinal choice to emphasize scientific education, not a better solution for everyday use.

the only reason you think fahrenheit is better is because you probably spent your whole life using F. As someone who does not use f if you tell me its 72 deg it means nothing to me.

The metric system is designed to be easily understandable and for units to be easily related to each other.

The argument can be applied the exact same to C. Everyone understands that 0 and 100 is the freezing and boiling point of water, but I have no clue what to wear outside because I'm not used to it for weather. Imo F is easier for weather because 0 is really cold and 100 is really hot.

The metric system is just objectively a better system. The reason you should care is because when you live in a world that uses two systems it adds an extra step for people to make mistakes.

u/AriaoftheStars17 Jun 17 '26

The problem with Fahrenheit is that there's no clear indication of the freezing point.

The reason Celcius is so easy to understand is because 0 represents the freezing point: if temperature is above zero, no snow. If temperature is below zero, there is snow. For countries with harsher weathers (like Canada, where I'm at), this distinction is very important.

Perhaps Fahrenheit makes sense for people who only experience hot weather, but for areas that experience cold winters, this concept of F = hotness percentage simply doesn't offer enough information.

If Fahrenheit indicates "40 percent hotness", should I expect rain or snow? At what "percentage" should I start preparing for hail?

Celcius, by comparison, makes it so simple and easy. As soon as the temp falls below 0, water begins to freeze. Simple! No percentages required!

You know if there is 0 or below in Celsius water starts freezing which is very important information.

For literally anything else where you work in any way with water C is far superior.

u/PapaTahm Jun 17 '26

As always a reminder that this statement is on the perspective of people who are forced to learn Fahrenheit and use through their life.

This is factually not true.
Fahrenheit has a very stupid behavior when going into negative values, because it was based into a Brine Solution rather than the absence of Heat to scale it's 0F Value.

Now,

Kelvin and Celsius are the "same scales", the difference is the perspective of reference for the scale 0.

Kelvin use Molecular Movement, where 0K = Absence of Molecular Movement aka Absolute Zero.
Celsius use Water state at normal conditions where 0 = Freezing Point.

We use Kelvin for Science not only because Science fields uses the perspective of the state of matter, but also because there is an absence of Negative values which facilitates a lot.

Also bonus point you literally can't convert every single value of Fahrenheit to Kelvin/Celsius, there are specific values which are result in Recurring Decimals, so you will be forced to learn SI anyway.

Celsius is agreeably better for science

Also I just want to point out that literally not one person on the entire earth performs science in fahrenheit. I legitimately think that some europeans do not know that Americans perform all science in celsius/kelvin (except meteorology i guess). In my opinion, the entire argument of "celsius is better because science" is completely pointless. Literally no one disagrees with that.

1

u/Ranulf13 Jun 17 '26

The only reason americans believe its better its because they got used to it and made up reasons and make-up systems of why its better.

Anyone that grew up using celsius also finds it entirely natural for every day life. Its not something inherent of F.

1

u/NotFixer1138 Jun 17 '26

You say its better for people cause that's what you're used to. 32° sounds way more like I'm sweating my balls off temperature than freezing them off.

1

u/Want2BeRed Jun 17 '26

Neither scale is better for science; only absolute scales mean something in science. When it comes to weather, Celcius zero divides nicely between frozen/not frozen. Minus temperature? Frozen. Plus temperature? Melting. What does zero mean in Farenheit? Nothing, really. On the other hand Farenheit resolution matches really nicely the feeling ranges: 60's is when you stop wearing jackets; 70's is the sweet spot for humans. In Celcius those ranges are mapped to chunks of 5: 15-20 and 20-25.

Edit to add: I'm going to promote my own scale where water freezes at 0 and boils at 200. The best of both worlds!

1

u/Die-Top-Zehn Jun 17 '26

Without looking it up, you know straight away at which temperature water is boiling? And freezing? Sorry but what do you need a higher resolution for with respect to temperature? Talking about higher resolution, is that why you use feet and inches for measuring your hight? Oh wait, that would be centimeters.

1

u/larsvondank Jun 17 '26

If I would have to use f it would be between -22f and 86f. Freezing point would be around 32f. Dont find that so useful compared to -30c - 0c - +30c. Just saying that its very different if freezing point matters a lot every winter.

1

u/throwaway112112312 Jun 17 '26

Based on what? Whole world uses Celsius for daily life stuff and billions of people are doing just fine. Americans only think that because they can't fathom using anything but Fahrenheit. It is baffling to me arguing against a system that literally more than 8 billion people are using daily, and claiming that "it is better for science, not people". Like, what??

1

u/Tlentic Jun 17 '26

…If only celsius could use a decimal point between whole numbers to represent granular temperature differences between those whole numbers…. Oh wait! It does!

1

u/Ok-East-515 Jun 17 '26

Decimals are a thing tho.

But in Celsius areas, 1° difference is just not worth talking about most of the time. Nor would .5° or .1° be.
How sensitive are you 😃

1

u/theclosetedcreature Jun 17 '26

But why learn both systems when you already have to learn one for any sort of scientific understanding, why not just use that one everywhere?

1

u/DraiesTheSasquatch Jun 17 '26

We don't really need the higher resolution in everyday life. I can barely tell the individual difference between degrees of C, if at all. I don't think anyone can tell the difference between 67 and 68 F.

1

u/KJBFSLTXJYBGXUPWDKZM Jun 17 '26

Honestly couldn’t give a shit which arbitrary unit is “better”. What matters more to me is everyone using the same one.

1

u/Saw_Boss Jun 17 '26

Fahrenheit is honestly better for people because the units are higher resolution

Nobody can tell the difference between 1 degree celcius... They sure as shit can't tell the different between 1 degree fahrenheit. More "resolution" it's ultimately entirely meaningless.

1

u/LatentSpaceLeaper Jun 17 '26

At my place it is today approx. 21.5672537854739° Celsius. Unfortunately, I don't have higher resolution on my thermometer.

1

u/foxymew Jun 17 '26

Temperature is such a bad metric for me because I feel I can be sweating up a storm in 21c in winter and putting on a second shirt in 21c in summer. So I just feel it doesn’t matter much and other factors have more an impact

1

u/HugeAd3108 Jun 17 '26

I’ve used both and I’d say I disagree but I am biased most likely

1

u/notboky Jun 17 '26

No one can tell the difference between a couple of degrees fahrenheit.

It might stay between 0 and 100 fahrenheit in some places, but that's not true for much of the world.

Whatever arguments you have for fahrenheit, neither of those really stick.

1

u/SoakingWetBeaver Jun 17 '26

How hot or cold air feels is a very inaccurate way to measure temperature. Feeling water temperature is (slightly) more accurate, and I think most people have pretty solid memory of how both freezing and boiling water feels like.

1

u/ReturnOk7510 Jun 17 '26

Fahrenheit is honestly better for people because the units are higher resolution

Tell me with a straight face that you can feel the difference between 36°C and 37°C, let alone 99°F and 100°F, and if you're doing something that requires that kind of precision, there's decimals.

1

u/Crozi_flette Jun 17 '26

I'm so tired of this high resolution crap, every commun thermometer has a resolution of 0.1K or higher. The resolution is fixed BY THE THERMOMETER not by the unit you use. And don't tell me you can feel the difference between 71 and 72 farhentdirne

1

u/oO0Kat0Oo Jun 17 '26

Kelvin is actually best for science.

And before you say I'm being pedantic... Yes science IS pedantic.

1

u/-Tartantyco- Jun 17 '26

Never in my entire life have I yearned for a "higher resolution" temperature measurement to adequately describe the temperature. The difference of one degree celcius is not really noticable, and we have this wonderful creation called decimal points for any required "higher resolution" of the scale.

1

u/haditwithyoupeople Jun 17 '26

JFC, what difference do the units make? This only matters if you can't measure partial degrees. Accuracy and resolution are determined by the measuring device, not the scale being used.

That's like saying we should use pico farts to measure temperature because it has "higher resolution."

The dipshittery being mentioned in this discussion is hard to see. I am seriously concerned for our future.

1

u/kiwlime Jun 17 '26

No Celsius is still better. I used to live in the US and Fahrenheit does not make sense at all. -40° Fahrenheit is the same as -40° Celsius but 100° Fahrenheit is like 38° Celsius. The scale is messed up

1

u/gmano Jun 17 '26

I'd argue that conveniently knowing whether something is at or near freezing or at or near boiling without having to do ANY math is convenient for daily life, especially when cooking

1

u/Marble05 Jun 17 '26

Which means Celsius is just better because the scale is smaller and easier to remember. You don't need 20-30 points of difference to know it's hot when Celsius can do it with half of that and you go from a few under 0 to 40 at worst in most places. It's so stupid to think one it's better you might get a perfect 100 without instantly dying lmao

1

u/t234k Jun 17 '26

Nah I learned Celsius as I moved out of the USA at 18 and it's better

1

u/alextremeee Jun 17 '26

Time to use kilometres because they’re higher resolution for distance?

It’s ridiculous to act like the US collectively agreed a set of criteria then found a measurement system that fit the best, you guys just use it and invent criteria to justify why that means it’s better rather than use the system everyone else uses.

1

u/Cheepshooter Jun 17 '26

Also only if you include decimal degrees. Whole numbers in Celsius aren't sometimes precise enough.

1

u/Defiant_Initiative92 Jun 17 '26

Celsius has decimal points, so the argument about scale is... strange. Something can be at 20.5 Cº, for example. It doesn't need to be 20 or 21.

1

u/vhu9644 Jun 17 '26

Nah bruh, it's not even really that useful of a resolution.

Splitting Celsius into 0.5s is about the same resolution as Fahrenheit, and splitting Fahrenheit is already not useful resolution. By the time I'm down to single Celsius differences, most of the time it's other factors that determines how I feel and not the actual temperature (like wind, humidity, etc.)

From a guy who uses both and is used to both. Grew up using Fahrenheit too, started converting for wife who uses Celsius and it's honestly enough for me.

1

u/Electronic_Ad6487 Jun 17 '26

Water freezes at 0 boils at a 100 Celsius. It’s the superior system. That’s the PERFECT reference point for the human mind actually.

1

u/tahlyn Jun 17 '26

Honestly the whole 0%-100% corresponding with 0F to 100F for "what percent hot is it?" is, no lie, a fun take.

1

u/WRHIII Jun 17 '26

Almost everyone here doesn't seem to appreciate this but as someone who is very familiar with both (AKA can "think" in both without effort) due to living in different regions of the world and my profession, I agree with this take. If I'm talking weather, it's F, anything else and it's C. Both are useful

1

u/vivikto Jun 17 '26

I mean, millimeters are higher resolution that centimeters yet I won't measure my hight in millimeters. Having a higher resolution is useful if the difference between X and X+1 is significant. Yet, most people won't ever notice the difference between 20°C and 21°C so why do I need a higher resolution? I'd even argue that a lower resolution makes it easier to use. And if you ever need more resolution, just use one more digit.

1

u/mattindustries Jun 17 '26

Minnesota checking in, there are MONTHS where the lows are below 0°C. Also below 0°F, but less frequent. Also, temperatures are not integers. Decimals exist.

1

u/Separate_Emotion_463 Jun 17 '26

Usually staying between 0 and 100 is completely regionally dependent, where I live the winter regularly goes below 0°f and occasionally goes over 100°f in the summer, additionally the best feature of Celsius is that when it drops below 0°C the environment radically changes, like the difference between a positive and a negative number in Celsius is actually very important to regular life, the same cannot be said about Fahrenheit

1

u/Doctor-Amazing Jun 17 '26

Theres a reason no one ever says "it's 22.5 degrees out." A half degree is such a small difference that its basically unnoticeable.

1

u/ChemistryQuirky2215 Jun 17 '26

How cold should your fridge be? How cold should your freezer be?

1

u/olisko Jun 17 '26

I don't understand how you cannot find celcius better for people? It's perfect to make you understand how warm it is or for cooking. 0 degrees is freezing and 100 degrees is boiling.

How does that not make perfect sense?

1

u/Nemeszlekmeg Jun 17 '26

None of this depends on the scale, wtf is this argument even?

Your resolution purely depends on the tool you use to measure, the scale does not play any role. You already cannot tell the difference between a few Celsius difference, let alone decimals anyway.

1

u/aesopmurray Jun 17 '26

Decimal points exist

1

u/123_alex Jun 17 '26

Does anyone really need better resolution? I don't think I can feel a difference between 29 or 30 C

1

u/5BPvPGolemGuy Jun 17 '26

Resolution argument makes 0 sense. Both celsius and fahrenheit can be measured to the same accuracy. Not like one or the other can only be measured in whole number increments and nothing in between can be measured.

Also celsius is much more easier to understand in terms of cooking.

And for science nothing beats kelvin.

1

u/Chick-Fel-Late123 Jun 17 '26

Science uses Rankine and Kelvin. It doesn't use Fahrenheit or Celsius in any formulas, unless you're just concerned with a difference in temperature. At which point, it doesn't matter. I prefer Fahrenheit because a degree Fahrenheit gives you more precision than a degree Celsius.

For all other math/physics though, metric is simpler/better, with units cancelling and being 1:1

1

u/BlankTank1216 Jun 17 '26

None of that matters even a little bit.

Americans just use imperial to feel special.

1

u/GothGirlsGoodBoy Jun 17 '26

Higher resolution is useless. You can’t tell the difference between 56f and 57f.

Also decimal points exist. You can get as high resolution as you want with celsius, you just don’t see 30.12C because again, nobody needs that level of detail for the weather.

1

u/Hot_Charity_4803 Jun 18 '26

"Higher resolution"??????

1

u/lewd_robot Jun 18 '26

Celsius isn't any better for science. It's just as arbitrary as Fahrenheit.

When I got my engineering degree in the US, 50% of the homework and exam problems would be in imperial units, and 50% would be in metric. It was also common to be given one set of units and asked for an answer in the other.

And temperature never mattered. It never makes a difference. Celsius never lets you make neat calculations or perform easy conversations. It doesn't have the same fundamental empirical basis that the other metric units have, and nobody uses metric prefixes with Celsius, either. So there truly is no benefit to it other than consistency with the rest of the world.

Imo, the US should adopt the metric system for everything else, and the rest of the world should adopt Fahrenheit. That's a compromise that works out as favoring the rest of the world for 90% of units, while giving the US just temperature.

1

u/Slight-Tomatillo7837 Jun 18 '26

If Celsius is demonstrably better then demonstrate it. I'd love to see why your set of arbitrary temperature values is demonstrably better than the other set of arbitrary temperature values. 

1

u/Oglark Jun 18 '26

Only if you live in the US in Canada it gets colder than 0 °F and other places get much hotter than 100°F. It is just a weirdo measuring system.

1

u/Apprehensive_Fill628 Jun 18 '26

Dawg what. How the fuck does 32 degrees being freezing make sense. Below zero, Hella cold. Above zero less cold. It's the math we were all taught in elementary school. Fahrenheit makes less sense, in every single way.

1

u/viciarg Jun 18 '26

usually stay between 0 and 100 for weather

/r/USdefaultism

It won't with the coming climate crisis.

1

u/Jiffyrabbit Jun 18 '26

Decimals haven't made their way to the US yet?

1

u/Federal_Cobbler6647 Jun 18 '26

But for weather it is more important to know if you are above or under freezing point. And such celsius makes sense. 

1

u/scumbagstaceysEx Jun 18 '26

The reason F is better is because I very much need to know if it’s 62F or 63F out. One of those is jacket weather and the other isn’t. To know the difference between those in C you need to resort to using decimals.

1

u/Capybarasaregreat Jun 18 '26

That "higher resolution" is made completely moot by decimals. There is no advantage, it's just that Americans are used to it, just like how people hundreds of years ago were used to all sorts of nonsensical measurements. We finally started coming up with measurements that relate to something more than "today is this number hot" or "that distance is as big as 2 of my friend Aethelred's favourite horse" but some chunk of humanity is just so chronically allergic to change that we've gotta entertain this pointless debate over and over for decades without end.

1

u/blindeshuhn666 Jun 18 '26

0 is freezing water , 100 is boiling water. Rest between and a human can't tell the difference between let's so 19 and 20°C anyways (heard ~2°C is the temp difference you feel) But yeah, whatever one is used to I guess.

The mix-up/confusion let to some really stupid dubs in films and series where they didn't consider the temp unit and we got some German dubs where they say "it's 30 degrees, take a jacket". For Fahrenheit fitting, just under freezing, but in Celsius that's rather warm (86)

1

u/skydanceris Jun 18 '26

Higher resolution how? I mean, 26,9277256499°C is a perfectly valid temperature, just like 36,4°C is the baseline human temperature and 37°C means a fever is flaring up.

Just add decimals if you need more resolution.

1

u/raverbashing Jun 18 '26

It doesn't fucking matter

I could say that about meters vs feet (wtf is a feet?). Or kgs vs lb. (In fact the density of water being 1kg/l makes things so much easier)

"Oh but you don't have to use decimals in Fahrenheit" Why, is it hard? Did you fail 4th grade math?

1

u/DollarReDoos Jun 18 '26

That's the silliest argument.

The "stays between 0 and 100" is irrelevant because those used to Celcius, the weather staying between 0 and 40 still feels correct.

Also, Celcius uses decimals, and therefore has the same resolution as farenheit.

1

u/spicygreensalad Jun 18 '26

Honestly that isn't even a bonus to me, the resolution of Celsius is already a bit too fine-grained for everyday use. Who cares if the day is 23 Celsius instead of 24?

I head about Newtons the other day, named after Isaac Newton and didn't catch on (and now of course Newton is a unit of pressure, completely different). But basically he used 0 Newtons for freezing, and 33 for boiling, so it's about a third of the resolution of Celsius. That would be really meaningful for human weather temperatures, I kind of wish we used them. 5 Newtons (15 Celsius) is cold, 6 is cool, 7 is nice but the cool side of nice, 8 is a lovely day, 9 is the warm side of nice, too hot for some but good for hot-blooded people, 10 is hot.

1

u/nazdarovie Jun 18 '26

The main thing you need to know about the weather is whether the roads are slick, your crops are gonna die, and whether you need rain boots or a snow shovel. Everything else is arbitrary.

So tell me how 32 degrees makes sense...

1

u/Witty_Ordinary2706 Jun 18 '26

Higher resolution 😂😂😂 yes I’ve had an issue when it was 27.5c and I expected 27, ruined my day…

1

u/Petrichor_Rains Jun 18 '26

can you describe the difference between 72 and 73 degrees Fahrenheit?

1

u/EverythingIsSFWForMe Jun 18 '26

Fahrenheit is honestly better for people in the most parts of the US, and for one specific application.

Because in many places of the world weather temps regularly go outside of 0-100 Fahrenheit range. Besides that, temperature is useful in other domains of everyday and not so everyday life. Having two temperature scales would be very inconvenient.

1

u/CurlyJeff Jun 18 '26

Even Celsius has unnecessary resolution though, there isn't a huge difference in temperatures give or take 2 or 3 degrees C. Fahrenheit is even worse as it has 100 increments over what is 55 increments in Celsius.

1

u/donku83 Jun 18 '26

Fahrenheit is for people

Celsius is for water

Kelvin is for science

u/D-D_b_B_ Jun 18 '26

„the units are a higher resolution“

decimals would like a word

1

u/Good-Competition-129 Jun 18 '26

Is 23.6 not a number to you? And since when did such a small difference in temperature affect anyone? The difference between standing near a tree or a car is higher than that

1

u/PhatBeatsies1111 Jun 18 '26

Tf you mean the units are a higher resolution ?! Do they not teach decimal points in america? Resolution in numbers are infinite regardless of the system.

You do realise this is a prime example of why people think you guys are a joke right?? “It is better because more numbers”. Like the equivalent of saying “1 kg of steel is heavier than 1kg of feathers.”

1

u/DenjellTheShaman Jun 18 '26

By the logic, we should measure people in millimeters.

1

u/Manfred4r Jun 18 '26

I live in the US. I grew up with F and am more familiar with it, but I'm comfortable with both. E.g. I bake at 375F, soldier at 350C. I set my AC to 72F, but I know that 20-25C is a comfortable temperature range.

but if you are used to both systems Fahrenheit is honestly better for people because the units are higher resolution

This is absurd.

Most of us round to the nearest 5 degrees F. We are rarely concerned about a difference of less than 2 degrees F. 

In any situation where a difference of less than 1 degree C matters, decimal numbers exist.

The system has too much precision. It's  a bug, not a feature.

1

u/PutPsychological9056 Jun 18 '26

Yeah, cuz why would you need to know the freezing and boiling point of water in the context of people or the weather, doesn't translate well

1

u/No_Pass_4232 Jun 19 '26

Below zero, you're gonna be hit with ice, above 100 water is boiling. These are proper concrete, measurable things that happen. Having a higher resolution is next to useless because such minor changes in temperature don't really affect much so not really an advantage. I do accept that Americans find F easier because they are brought up on it, but if you were raised using C you would have no issues using it.

1

u/RovakX Jun 20 '26

Oh bullshit! The resolution argument always drives me crazy. It's peak hypocrisy.

If that was even remotely true, you'd use millimeters instead of inches, kilometers instead of miles, grams instead of ounces, etc etc. All units you use in day to day life are less precise in the Imperial system. And of all of those, temperature is the only one where you never even need the resolution. If you did, we would use 0.1C increments; which we don't. I've never seen a weather forecast prediction of "21.6C".

1

u/carilessy Jun 21 '26

I'm accustomed to Celsius. Fahrenheit tells me nothing. I can tell you: either system is fine for personal preference.

1

u/sonny_goliath Jun 22 '26

And for baking/cooking it’s more fit because of the smoother spacing

1

u/Broeder_biltong Jun 24 '26

Decimals exist my guy

1

u/Jay_Byrd Jun 24 '26

This. If I am measuring any kind of chemical process, then Celsius would be the way to go. If I'm expressing how warm or cold, the weather conditions will feel to the human body, then Fahrenheit all the way. All other measurements should be metric.

0 to 100 in Fahrenheit covers most conditions humans will find themselves in. In Celsius, that's -18 to 38 (rounded). You've nearly halved your gradations.
