I've used C all my life, but moved to the US lately and trying to start using F.

Probably the easiest measurement change to get used to. There's very little difference in actual practice.

C makes it easier to reason regarding freezing/boiling - it's simpler to think about if it's going to snow by relating it to 0 then 32. But that's about the only difference in day to day use I can think of.

I haven't heard any reason to prefer F over C however (unlike Feet for example).

here is a counter-anecdotal evidence I moved to the US 25 years ago, still hate F with passion

I gave it a serious go. After trying to get used to F for 20-some years, I went back and set all my thermometers and online weather maps to Celsius.

Farenheit is an absurdly bad scale choice. It is needlessly granular for everyday use and feels wholly arbitrary.

32 degrees is freezing, so how far is 19 F from freezing? 32-19 ... ummm 13 degrees and that is as far as 32+19 ... ummm 51 degrees ... what are we talking about? -10 and +10 Celsius ...

I still don't know if 120F would burn my hands or not, if 150 F scalds or not. I have no sense about temperatures above 100F (and that one only because it is a threshold for fever)


> I still don't know if 120F would burn my hands or not, if 150 F scalds or not. I have no sense about temperatures above 100F

I don't see how C would be easier for that. How do you know if 49℃ burns or 66℃ scalds?


My gut sense is that is that over 50C you are getting into scalding territory.

50, which is halfway between 0 and 100, so that, too, kind of makes sense.
