As an American this is how I interpret Celsius

  • 100 is boiling
  • 50 is you're gonna die from heat exhaustion eventually
  • 40 is hot
  • 30 is a little warm
  • 20 is a little cool
  • 10 is cold
  • 0 is freezing

    As a Norwegian:

    • 100 is boiling
    • 40 is we all gonna die
    • 30 is hot
    • 20 is a little warm
    • 10 is a little cool
    • 0 is cold
    • -5 is maybe time for a jacket
    • -10 shit, it's freezingly cold outside!
    • -15 I'll stay indoors if I can

    I regularly convert between the two just by remembering the conversions for 10, 20, 30, and 40. It's actually pretty easy.

    • 0C is 32F (of course)
    • 10C is 50F
    • 20C is 68F (a cool room temp)
    • 30C is 86F (reciprocal of 20)
    • 40C is 104F

    If you ever forget what one of them is, then just add 18F for every 10C from the last one you remember.

    Metric:

    10 mm = 1cm, 100 cm = 1m, 1000 mm = 1m, 1000m = 1 km.

    1 cm3 water = 1 gram

    1 Watt heats 1 gram of water 1 C°

    1 dm3 water = liter = 1 kg

    1 m3 = 1000 kg = 1 tonne

    Imperial:

    1 mile = ?? yards = ?? feet = ?? inches

    1 ton = ?? stone = ??punds = ?? oz = ?? grain

    1 Galon = ?? pints = ?? fluid ounce

    1 inch3 = ?? grain = ?? power to heat ?? fahrenheit

    There is no system to any of these, they are unscientific and impractical.

    How does Imperial still have any relevance as a measurement system?

    That's exactly how I've memorised imperial as well. We must have used the same manual.

    Yes, you could say Imperial is easier, because you'd never calculate anything in your head, you ask Google.

    But how did that even work before we had Internet?

    I suppose they had little booklets. A bit like the logarithmic tables that people kept for complicated calculations. Maybe they were issued on the first day of school or something. People would keep them all their life and look at them surreptitiously whenever they had to convert units.
