They’re pretty much part of the guardian’s dna:

If you want "twice as hot" to be meaningful, you have to use an absolute scale, either Kelvin or Rankine. (1 K = 1.8 °R) Doubling absolute temperature doubles the pressure (at constant volume) or volume (at constant pressure) of an ideal gas. This gets really important when it comes to compressing and expanding air and other gasses.

Room temperature is approximately 293 K, twice that is 586 K / 595 °F / 313 °C. Hotter than your typical oven cooking temperature.

We often don't realize how warm the world we live in truly is, from a physics standpoint.

Kelvin doesn't use degrees

Why do we use degrees for other temperatures by the way? Is that related to some kind of absolute vs relative metric? (Kelvin, I guess, is based on absolute zero as a reference point, doesn't it?)

Incidentally, why is the degree immune to disappearance in division unlike all other units? That is, if I divide a distance (m) by a speed (m/s) I get a duration (s). From sheer memory, degree doesn't work like that. Any clue why?

Degrees aren't a 'unit' indeed because the zero point isn't a real zero. Hence you don't get correct scaling.

Hard? So is using the degree symbol apparently: not a single one in the whole article. (68F is not a temperature — it’s a seat number.) https://degreeswhat.com/?68

"To be fair", there is ASCII in the name

I appreciate the ASCII-only excuse, but I've corrected the omission anyway. Non-ASCII characters in randomascii - what will they think of next?
