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.
No argument here. Fahrenheit offers better granularity within the range of temps that humans are likely to experience.
Except you don't actually need that level of accuracy when talking about temperatures humans experience.
For example, has the ability to identify outside temperature of 72 fahrenheit, not 71 fahrenheit, ever made a single bit of difference to any persons day to day experience? I really can't believe that would be true.
Places that use Celsius have no problem referring to temperatures for weather so the argument that farhenheit scale is superior due to more precision doesn't hold up.
The best temperature scale for weather is always going to be the one that everyone in that area is familiar with and nothing more than that.
