Iv always found Celsius makes way better sense for material tempature and Fahrenheit for the weather.

Celsius is no where near granular enough for the weather not by a fucking long shot.

I rather use the arbitrary jacket scale and shorts scale then Celsius for weather.

Is it jacket weather or shorts weather are the only two criteria. And it varies person to person and has zero ability to be translated between people. Yet everyone understands it natively and intuitively anyways.
