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

It's another question how they obtain that from coulombs...
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. Hotte…
When talking about the weather or everyday objects, one could argue that the border between "hot" and "cold" is somewhere at room temperature, so around 21°C. At that temperature, it's neither hot or cold. If it's 30°C, it's 9°C of "hotness", so 39°C would be twice as hot. I don't know if it feels twice as hot, as that's quite subjective, but if you want more precision we should switch to another vocabulary entirely.
Earlier quoted context omitted.
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 cl…
Degrees aren't a 'unit' indeed because the zero point isn't a real zero. Hence you don't get correct scaling.

Correction, 68°F.
> So 20 °C is either 78 °F
It's still 68°F.
