Fahrenheit is based on human experience:
0° is fucking cold. 100° is fucking hot.
Celsius is based on at sea level water:
Water freezes at 0° and boils at 100°
A. Celsius is flawed because water freezes and boils at different temperatures depending on altitude.
B. When I ask what the temperature is, I’m asking for myself. I don’t give a fuck how water feels about the weather.
