I feel the same in the other direction; it's weird to me that 0-100 isn't a normalized range, and instead some (seemingly) random numbers in the mid 30's is the upper bound for human comfort.

I don't think about if water is cold or hot -- I think about if I'm cold or hot.

Why do I need to know if water is boiling in relation to what I wear when I go out?

If we're going to index on a base 10 number, it's better to index on the human experience of temperature, not the scientific measurement.

You lose half the scale in fidelity when using C.

F is superior in every way.

0C: Cold
100C: Dead

0F: Cold
100F: Hot
