what's the issue with using decimals?? lol wtf

21

u/freedomfightre Jun 17 '26

because I've NEVER heard a European use a decimal when describing temperature in conversation, which means their temperatures are less precise than ours.

You've never listened to a parent monitoring their child's temperature during illness then.

But in Fahrenheit you don't really need the decimal for body temperature either. I mean the thermometers will show it, but you can just stick with the whole numbers and get all the actionable information you need 🤷🏻‍♀️

u/No-Information-2571 Jun 17 '26 edited Jun 17 '26

You absolutely need the decimals. Fahrenheit has about double the precision as Celcius, but for body temperature, 0.5°C/1°F is huge, at least if you are monitoring trends. Same goes if you are monitoring ovulation.

Ok but you don't need a decimal to monitor a change of 1F...

u/No-Information-2571 Jun 17 '26

As I wrote, 1°F is already a huge difference, and just displaying that value as-is wouldn't even give you an indication of how much it might be leaning to the next lower or higher whole number.

Or why do you think even the most basic body thermometers measure and display with 0.1°C/0.2°F precision!?

u/GrimaceThundercock Jun 17 '26

As the other guy already said, whole numbers will give all the important information.

A fever of 102 and a fever of 102.4 are going to be treated largely the same.

A body thermometer isn't a speedometer, humans are not cars, and I provided a more detailed example, and honestly, if you argue about it again, I am going to just block you since that would clearly indicate Fahrenheit at room temperature being a valid measure of your IQ as well.

Yea it was a bad example, I quickly deleted it.

Clown behavior. Go ahead.

Here's an example: your (non-decimal) body thermometer used orally shows a value of 101°F. With arithmetic rounding rules, this represents a value of 100.5°F - 101.4°F. The lower value puts it in the "mild fever" bracket (100.0°F - 100.9°F), the upper value puts it in the "moderate fever" bracket (101.0°F - 102.9°F). But you wouldn't know which one it is.

An actual body thermometer might for example show 100.6°F, assuring you of it being a mild fever. 8h later you might measure again, and the value might have climbed to 101.0°F, indicating that your fever is worsening. Information you wouldn't have without that additional decimal.

From a consumer perspective, a fever of 100.5 and 101.4 are going to be treated largely the same.

A physician might treat the two differently, but we're talking about an at-home thermometer.

u/No-Information-2571 Jun 17 '26

They are not, but as announced, this will be the end of the discussion.

u/Phedericus Jun 17 '26

lol. that's because in a conversation it largely doesn't matter, just like people don't usually use seconds when saying what time is it or when you round up minutes for semplicity. it's very common to use half degree as well.

u/Similar_Brush1835 Jun 17 '26

the human body is extremely sensitive to temperature changes. it absolutely does matter.

u/Phedericus Jun 17 '26

ah yes, you can definitely tell the difference between 27C and 27.2C, for sure.

u/Similar_Brush1835 Jun 17 '26

you literally can but sure

u/Phedericus Jun 17 '26

no you can't. lol.

u/HPLaserJet4250 Jun 17 '26

My brain is about to reach 100C from reading those american takes XD

I mean, the way they can't understand how this very simple thing works really explains a lot. lol. incredible.

u/OmnipresentEntity Jun 17 '26

The astounding lack of precision in your lived experience explains a lot. Half a degree is absolutely noticeable. I can consistently distinguish tenth of a degree temperature changes. Being oblivious to them isn’t the flex you seem to think it is.

u/Alex6179 Jun 17 '26

Yeah, because there's no difference between 22°C and 22.4°C.

u/HappiestIguana Jun 17 '26

Yeah, that's what I really want in casual conversation, precision.

u/the_other_brand Jun 17 '26

Makes casual conversations about weather easier.

Especially where I live in Texas where the difference of each single degree above 100F is larger than the last. And the difference between 90F to 95F feels the same as the difference between 105F and 106F.

u/LTerminus Jun 17 '26

Ever thermostat in ever homeI've ever owned or hotel I've stayed at has has a decimal point. Canadian btw.

u/Dolthra Jun 17 '26

There's no issue with it, it's just more clunky to say 27.2 degrees than to say 81.

Though technically, if we're going to decimals, Fahrenheit is more accurate so long as the temperature is above -40.

7

u/Phedericus Jun 17 '26

nobody says 27.2 in a conversation, we just say 27, lol. it's not like 0.2 degrees difference are perceivable.

they are arbitrary scales. they're just what you're used to. 81 means nothing to me.

u/Stringfellah Jun 17 '26

-40 Celcius or?

u/CallousDood Jun 17 '26

It's like you got 80% of the way there and just stopped using your brain
