Kelvin is for scientists.
Celsius is for people.
Fahrenheit is a translation layer between Celsius and Americans. All their weather stations have been Celsius for ages, it's a societal decision to use an arbitrary unit instead. The "69F censoring" which turned out to be a rounding artefact illustrated that nicely. Their government could change that, power to them that they decide not to 🤷♂️
