100 F is roughly a human's body temp. (Actually 98.7 avg, but close anyway)
0 F is goddam cold. (This one's pretty arbitrary ngl)
That probably isn't very helpful.
Fwiw, Celsius isn't much better if you didn't grow up with it. 0 C is pretty cold, 100 C can give you severe scalds. The actual range the people will encounter in weather in their day-to-day lives is all over the place regardless.
Perhaps we are destined to stay divided
