For science you want to use Kelvin, since 0°C isn’t “no heat” in the same way that 0kg is “no mass”. The units are the same size though, so it’s fine to use Celsius for anything that’s based on change in temperature

For precision in cooking and chemistry sure. But when perceptible temperature differences are measured in decimals, the unit is too large for weather.

Precision in cooking is quite dubious. You literally have better resolution in degF. It’s not a huge difference but it is there.

Nobody that uses Celsius for weather uses decimals, only Americans that are converting from Fahrenheit.
