> Probably the easiest measurement change to get used to.

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)
