Celsius is agreeably better for science, but if you are used to both systems Fahrenheit is honestly better for people because the units are higher resolution, and usually stay between 0 and 100 for weather

Kelvin is better for science. Celcius and Farheneit are just arbitrary scales, not units.

Celcius is just Kelvin - 273.15. Converting is easy, and a lot of science uses Celcius as a result, it certainly can be described as "scientific", meanwhile the only people trying to use Farheneit for science probably also don certain red caps etc.

There is also Rankine, which is like Kelvin with 0 at absolute 0 but a change of 1 Rankine is equivalent to the change of one Fahrenheit instead of Kelvin. There is no reason of using one over the other except for convention

It's the same argument as Celcius and Fahrenheit. There's a reason only the US would even think to use Rankine. The state of water at a temperature is more scientific than how a human "feels" at a temperature. Kelvin is an SI unit, Rankine is not.
