I talked with an american so i of course used ammo (9mm) as a scale
I will be controversial and say that I think Fahrenheit makes more sense when talking about the weather. Its scale simply makes more sense on human terms: 0 is fucking cold, 100 is fucking hot. This is about the tempurature range you can expect to experience between winter and summer throughout much of the world.
Celsius makes more sense for cooking (and everything else) since its scale is calibrated around the phase changes of water.
Cause 30C is warm but 39C is heat stroke. Bigger range than 80-89F (warm to really warm), 90-99F (hot to really hot), 100F+ (heat stroke hot).
I very rarely hear anyone refer to air temperature with a decimal though.
We don’t even need that for weather. There’s not that much of a difference between 21 and 22 C, and anyway with wind and shade you can quickly have a difference of a few degrees.
Same the other way around. I (european) regularly read about “100 degrees weather” somewhere in the US and my first thought always is “damn, that’s as hot as boiling water”.
