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
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.
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.
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.
Unpopular opinion time; the US already uses metric/Celsius where it matters; in science, engineering and the military. Where it doesn't matter, we use a weird hybrid system that makes intuitive sense to us and is accordingly perfectly functional and doesn't need to be changed.
Farhenhiet and Celsius are equally made up. All measurement systems that we use on human scales are made up.
And in this case, farhenhiet is actually just better. More granular and more useful on a day to day basis. Yeah, it doesn't have the freezing point of an arbitrary substance as the 0, nor the boiling point of an arbitrary substance at 100, but it has temperature you should immediately be concerned about coming into contact with outside of -20 and 120, temperatures you should be concerned about contacting outside of 10 and 90, and fairly normal weather between those two.
