Actual poster from 1917 that made me laugh. A lot.

Also, those motherfuckers are measuring the weight of those balls in kilograms, aren’t they?

      Km is 103m cm is 10-2m so the difference is 105 i.e. 100000 (one with 5 zeroes)

      Or more intuitively one centi-meter is a 1/100 of a meter and Kilo-Meter is 1000 meter therefore 100*1000 100000

      It is quite intuitive, once you start using it

      What’s weird is why we don’t use Megameters and megagrams (i.e. one metric ton)

        How many liters is 1 square meter of 1mm thick steel?

        I’m definitely on board for megameters. One AU is about 150 gigameters and 1 light year is about 9.5 terameter!
