Yeah like the metric system has good arguments for why it's measurements and weights are better, mainly conversion being easier, but for temperature there really isn't an argument. I would make an argument for Fahrenheit as it gives more precision without having to use decimals which at least in America isn't a thing for temperature. But those are pretty minor things and I do tend to agree it comes down to what you grew up with.

without having to use decimals

This fear of decimals is a strictly American thing. Celsius achieves more precision with decimals than fahrenheit without decimals. And this American fear of decimals is pretty funny, considering you will happily do advanced fractions as soon as you are doing length measurements.

I don't mind decimals at all, it's more that I don't trust companies to actually deal with supporting decimals when making the switch. Plus the last time I discussed this on Lemmy someone was saying that decimals aren't even universally used and it might depend on what you get whether you get that precision or not. Either way like the main point of my post was anyways these are minor arguments and at the end of the day there isn't really a reason to use Celsius vs Fahrenheit.

Can you feel the difference between 23.5° and 24? I can't. You don't often need precision to tenths.

In Australia most weather providers give you whole degrees, the bureau of meteorology gives you to one decimal in reports and whole degrees in forecasts

My coffee and beer boilers can hit high precision temperatures to variously 0.1° or 0.5° precision. The beer boiler gives 3 digits - hundredths below 10°, tenths below 100°, whole numbers 100° and over

You can choose the precision of thermometers you wish to buy for yourself

I have seen fahrenheit thermometers which are hard to read to better precision than 5 degrees

1cm3 of water weights 1 gr and needs 1 calorie to rise 1ºC.

But calories are now obsolete and the unit is Joules.
