    Never understood the fidelity argument. It’s not like decimals suddenly stopped existing because we’re dealing with temperature.

    As far as measuring weather, they’re more or less the same. Fahrenheit is handier on the high end but useless in the low (0F doesn’t mean anything). Celcius is a lot more useful at 0, and then the higher temperatures are around 30-35 which is fine, but as cool.

    Where celcius shines is when you start combining it with other units like calories and then Joule and Newton, etc.

      90 f was the average temperature of the human body. 0 in fahrenheit used to be the eutectic point of water and ammonium chloride. Eventually though, the scale was adjusted so that the lower point was the freezing temperature of water (32 degrees) and the upper point was the boiling point of water (212 degrees) this was chosen so that there would be a highly divisible number between them (180) due to this adjustment, 0 isn’t special in fahrenheit, and neither is 90.
