TIL about the Delisle temperature scale, where the scale increases as temperatures get colder and decreases as they get hotter. Absolute zero Kelvin is 559.73°De and the temperature of the sun is -810

The Delisle scale is notable as one of the few temperature scales that is inverted from the amount of thermal energy it measures; unlike most other temperature scales, higher measurements in degrees Delisle are colder, while lower measurements are warmer.
