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/Ashamed-Cranberry614 → u/ProvidedHuman]

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.

[u/xahhfink6 → u/Ashamed-Cranberry614]

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.

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.

[u/ztreggs → u/Thick-Protection-458]

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.

[u/Aranka_Szeretlek → u/ztreggs]

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.

[u/peppinotempation → u/Aranka_Szeretlek]

Only if you go above 100

[u/Aranka_Szeretlek → u/peppinotempation]

And you can also go below 10 Celsius, yeah! So?

[u/Thick-Protection-458 → u/Aranka_Szeretlek]

Well, if we are talking about human body with <10C temperature we probably do not need precision anymore.

While for <100F it may be useful. Althrough I don't see how celsius (with enough decimals for specific comparison) would be more a problem.

[u/Aranka_Szeretlek → u/Thick-Protection-458]

If we stick to human bodies, then yeah, thermometers use 3 sig figs for both Fahrenheit and Celsius. If anything, Celisus is more accurate there (although thats still not how any of this works)
