F is not superior to C, your argument for it makes very little sense, even from a plain human "everyday" (non-scientific) point of view. Can anyone sense when the temperature changes by a single degree in F? I doubt it. With C you have a chance. With C when it's below zero you know there could be snow and ice.

Each set of 10 degrees in C is a pretty clear temperature range. 30-40 scorching. 20-30 hot. 10-20 warm. 0-10 cool. -10 to 0: cold
