As a dweller of a cold place in the USA, F is pretty handy because "freezing" isn't terribly cold. Having 0F be "actually quite seriously cold" is useful.
My parents care a lot about "przymrozek" - which is when it gets sub-zero C at night and you need to cover the plants and close the greenhouse doors and put a heater there so the plants survive. They give warnings in radio when this happen outside of regular winter months.
There's also special warning for drivers if it was sub-zero because then the water on the roads freezes and it's very hard to break.
I'd say it's way more important a distinction than anything that F makes obvious.
We just need a new scale just for weather where 100 is 100F and 0 is 32F/0C then everyone can be happy. We'd have a lot more days with subzero temperatures though
I do agree, though I live in Europe and C is the norm. I could never wrap my head around F.
That said, I think 0 is more important in daily life, below or above freezing. How much is that in F again?
