As an American engineer, I see the value in Celsius over Fahrenheit, so I've been slowly changing all of my references to temperature, like my weather app, the weather units in my car, etc. to Celsius.

Didn't take that long to get used to it as long as you associated different weather "feels" with multiples of 10.

0 °C = obviously cold and I need pants and an overcoat

10 °C = chilly on a wet rainy day, pants and maybe a sweater or jacket

20 °C = comfortable, shorts and a long sleeve if cloudy or short sleeve if sunny

30 °C = hot, definitely shorts and a T-shirt

Americans are resistant to change though, so I don't expect this to take off anytime soon.

if you make your judgment based on the 10s then you're using a bloated scale, like those mobile games where characters have 6 digit hp and you try to beat them with 4 digit damage numbers.

All these linear temperature scales. Does anyone know any logarithmic temperatures scales? Asking for the kid of a friend.

Ice cold -- 0 degrees.

Who wants Ice at 32 degrees? That's a ridiculous temperature to say "It's freezing out there -- it's 32 degrees!!"

If I want someone telling me it's cold, I want it to be sub-zero. Not sub-32.

You know I'm right.

The real kicker is the temperature relative to what you're used to, tell and Australian is 15c outside and they will put on a jumper, tell a Scotsman it's 15c outside and they will strip down to their shorts and go swimming.

Hahaha. No, but seriously, we gotta switch to metric. I hate owning 2 sets of tools.

Also, it's easier to think, "Oh, 10mm is slightly too small. I need 11mm." instead of "Oh, 69/420ths of a barley corn is too small. I guess I need 70/420ths?? Wait, they don't make that size? Oooh, nooooooo!!!! AAH!"

Celsius is better because the portrait of Anders Celsius on his wikipedia page has the same expression I make when someone says that Fahrenheit is better https://en.wikipedia.org/wiki/Anders_Celsius#/media/File:Headshot_of_Anders_Celsius.jpg

Fahrenheit is better because 69 is nice and zero has far more chill.

I know I'm literally taking the bait with this, but the argument about saying it's 10s in Celsius Vs it's 70s in Fahrenheit makes no sense, because you would just say the number or high/low/mid 10s and that tells you everything you need to know.

I've wondered: do celsius thermostats normally have half-degree increments? In my house I found that a single degree F matters to people, and for celsius it's too big of a swing.

I'd like to clarify that Celsius is used with commas.

My temperature sensors don't read rounded numbers, they read 21.7 for example. A forecast uses rounded numbers because it's a ballpark anyway.

Doesn't that make Celsius more granular than Fahrenheit on the same range?

Midwest: "what are you talking about, of course 10 degrees is shorts weather! Oh... You mean Celsius?"

Shouldn't we have a measure that combines temperature with humidity to tell what to wear?

I say we abandon numbers entirely for air temps in non-scientific environments.

Frigid -> freezing -> cold -> chilly -> mild -> warm -> hot -> scalding.
Everyone reading this knows exactly what those temps are regardless of numbering system.
