We’re taught both metric and US customary units in school. I prefer metric for most things, to the point I have a metric-only tape measure among other things.
However, I’ll die on the hill that Fahrenheit is superior for ambient air temperature. 0 degrees to 100 degrees neatly encompasses the range of average surface temperatures seen throughout the year in the contiguous US.
I remember my sophomore thermodynamics class in college always seemed artificially hard because the only really difficult problems were ones where they decided to use fucking BTUs.
I’m reading the wiki and that sounds like hell. I prefer the 4200J/kg/K edit: wait that’s just heat capacity, maybe you were stuck in even more hell.
