If those Americans could read they'd be very upset.

I just use

30°C is hot, 20°C is nice 10°C is cold, 0°C is ice.

Obviously that won't apply everywhere, but in milder climates it works pretty good.

For the other Americans that came into the thread hoping to see a conversion:

• 10c = 50f
• 30c = 86f

Edit: I'd like to note that 10c is a very reasonable temperature for shorts. I'm a Minnesotan (basically Canada lite (please annex us)), people start raising eyebrows at around 0C

Paraphrasing an old meme:

Fahrenheit - how hot humans feel
Celsius - how hot water feels
Kelvin - how hot atoms feel

C° or °C bud?

Jokes on you. I'm an american who works with scientific equipment so I mainly work in Celsius. Also live in Minnesota so we get the best of both worlds. Last winter hit almost -30C at times meanwhile tomorrow has a high of 39C with almost 70% humidity.

Americans know about °C, but what the hell is C°?

I prefer free health care units

Most kids don't get degrees.

I certainly know what degrees Celsius are, but I have no idea what Celsius degrees are supposed to be.

Why does the US live rent free in so many European's heads all the time?

Fuck it, it's 8 o'clock and 28°C with 60% already. We are not used to this shit here.

Here's a rough C° primer for Americans

0° or below, fucking cold

1° - 10° cold

11° - 20° cool

21° - 30° warm

31° - 40° hot

41° or above - Jesus Christ I'm on fire!

As for Fahrenheit for the rest of the world, on a scale from 0 to 100, how hot is it? Assume anything below zero is really fucking cold, and anything above 100 is really fucking hot.

Kelvin gang

I don’t know if they stopped, but American kids at least used to be taught both Celsius and Fahrenheit. At least in some parts anyway. I was taught both as a kid, with my school largely banning the use of Fahrenheit by staff on campus even, for instance.

I was taught both.

Just like I was taught both metric and imperial.

I use both temp scales, though fahrenheit is more common.

I use both measurements scales, though imperial is more common.

One thing I've never understood though. Metric is more precise for measurements (at least without needing to involve fractional measures). I totally get why it's superior for a lot of things, and indeed it is used in many places for this exact reason.

Why would anyone say Celsius is better? Apart from freezing and boiling temps seeming somewhat arbitrary with fahrenheit, does it not allow for much higher precision with regards to temperature identification without resorting to decimals? Isn't this the same rationale used with metric vs imperial? It seems like a double standard to me, because remembering two temperatures (for boiling and freezing) seems like a small price to pay for a more precise system.

Shorts in 10C is standard practice for me. Really not that cold for us in the NorthWest. Now if we're talking Southern Californians 10C is heavy winter jacket weather.

American here. Always knew C temps.

10 c cool 20 c perfect 30 c ok I need shade and a body of water 40 c wtf 50 c I’m dead

30 is hot 20 is nice 10 is cold 0 is ice

Double Celsius and add 30. It'll get you close enough for environment temps.

10*2 is 20, plus 30 = 50.

(10°C × 9/5) + 32 = 50°F

30 doubled is 60, plus 30 is 90.

(30°C × 9/5) + 32 = 86°F

10°C is mild af. Who tf doesn't wear shorts when it's 50F?

If you want to sound more metal, tell people how cold it is in celsius. Was it kinda cold or was it in the negatives?

Me, an American, laughs in PC temperatures always being in C
