Celsius works significantly better in cold climates for reasons mentioned in another comment.
In my old apartment, the difference between 73F and 74F was enough to make me quite cold or hot. And that’s a difference of about 0.5C. I’m not arguing that Farenheit is better, but I definitely do prefer it for setting my thermostat (which is a day to day thing) , but then again I grew up using it so that could be why I prefer it too.
Probably because they were made for US and changed the labels? I've never seen a thermostat with 0.5 C increments in Europe.
> the change between 25C and 26C is actually pretty big
I would maybe be able to tell you if it's 23 or 27, certainly I can't tell 1 C difference.
