That last bit is the key: Fahrenheit also fits the mental model of normal human communication quite well if you use it.

The F vs. C wars are silly; if you were raised using a particular unit system, then that system will most likely feel the most natural to you. If you didn't, you can certainly learn another and adapt, but for most people it won't feel right.

This is all just fine. Yes, it's annoying when you travel to a place that uses a different unit system than you're used to, but life is full of such things, and we should just live with it rather than trying to argue what's "right". Nothing is right, nothing is wrong. Whatever is, just... is.

(Note that I'm not making any arguments about which one is better for math or science or whatever. Just about what feels comfortable. For the record, I do think many things -- including global interop -- would be easier if we all used metric. But I don't think, no matter how hard I try, I'll ever be able to "feel" celsius properly.)
