alt Hacker NewsCelsius in a lab (or in cooking) is perfectly fine.
But as a way to describe daily weather (and thermostats) it's woefully inadequate.
The sum total of "comfortable" temperatures in celsius has to be squeezed between maybe 17 to 24 - why? you never ever use anything above 40 except when talking about people that died from a heatwave.
It's based on the freezing and boiling point of water _at sea level_ which almost none of us ever encounter (whether it's sea level, or the boiling point of water).
Fahrenheit is a much more intuitive scale (again... to describe daily weather or human temperature) - 0 - 100 better models the temperatures we experience daily, and you can intuitively separate into 10s, the way you "feel"
For example...
100s - honey, please, let's move to a cooler place.
90s - uncomfortably hot
80s - hot in the sun, not too bad at night
70s - you'd probably want a light sweater at night
60s - light sweater all the time
50s - medium sweater
40s - sweater, maybe a coat
30s - coat
20s - sweater and coat
10s - why am i living in this region?
0s - honey, please, let's move to a warmer place.
The point is that there's enough resolution to describe the actual human experience with temperature.
For everything else, celsius is perfectly adequate, totally agree.

Celsius has plenty of resolution for this; in fact I would say Fahrenheit has too much. You can feel the change of one degree Celsius, you can’t really with Fahrenheit. To illustrate this, not only is your scale in tens, but I often only hear people quote the Fahrenheit temperature in tens. In Celsius we almost always give the whole number, because it makes a difference.
They also accidentally got MPH right for cars. Fastest highway is like 85. 100 is the fastest a normal car can go and also a reasonable point to arrest the driver.
You can make pretty much the same chart for Celsius and it makes as much sense.
40 - scorching hot
35 - super hot
30 - sunny summer day
25 - nice warm weather
20 - nice breezy weather
15 - a little chilly
10 - bring a coat
5 - getting cold
0 - drivers be careful
-5 - is cold
-10 - seriously cold
Etc.
Body temperature also has a nice cutoff point of 37.0C before you start to worry.

30° is perfectly comfortable for me.
FYI, none of this has ever made any sense at all to somebody who didn’t grow up with Fahrenheit. Numbers don’t need to go roughly between 40 and 100, and then occasionally 212 and 450.
The difference between 20 C and 20.5 C is not generally noticeable. The difference between 20 and 25 really is.
You’ll just have to face the fact that you feel comfortable with a really weird system that nobody else can see the point of, but it’s what you’re comfortable with. That’s OK, you’re allowed.
