Unfortunately, service technicians acknowledged a physical hardware fault: ice buildup jams the internal flaps, trapping refrigerant and stopping the compressor… "

    For uncultured Americans like me, -10° C is +14°F, a temperature regularly seen in winters in the northern 1/4 of the US.

    The only C/F temperatures I ever remember are that -40 are the same, 100 is 212 and anything above 32 is too fucking hot.

      22-24 is comfortable room temp (71.6-75.2⁰F)

      37 is body temperature (98.6)

      40 is a bad fever that might kill you (104⁰F)

      To quickly convert, take Celsius and double it and add 30. For human scale temps you’ll be a few degrees off at most. Not so much for deciding what temp to smelt your steel at though.

      F->C subtract 30 and then halve the result.

      130F -> 100 -> 50ish (54.4C)

      Where I live -10⁰C is nice and warm for half the year. -20⁰C(-4⁰F) to -30⁰C(-22⁰F) is normal most of the winter.

      Also neat fact, if the degree symbol comes after the unit, in a metric engineering that means a difference of.

      50⁰C - 35⁰C = 15C⁰
