Originally I thought it was talking about age.
Its not the wrong unit, we just forgot how to update it and its working well enough. Also bite me I dont want to deal with decimals to know the tempeture on a more accurate level.
I dont know anyone who uses decimal when they use celsius.
Well my cars Celsius setting certainly does. Fucking things weird though so IDK.
I also realized my american appliance do this same when I try to set them to celsius (nest etc). I guess that is where this unfortunate misconception comes from.
Various groups in the US have tried to convert and it failed because… There’s absolutely nothing wrong with the current system and very, very little to be gained by switching.
