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?

    The calorie used to be the base unit, until we released in the 19th century “wait, heat isn’t a gas” and threw out caloric theory, and made the joule. Now the calorie is defined as 4.184 joules.

      Yes, you’re right.

      There have been multiple iterations of the “metric system” since it’s introduction in 1792–1795, most notably the original 1795 draft variant, then the CGS (Centimeter-Gram-Second) version, then the MKS (meter-kilogram-second) variant, with the most recent incarnation being the International System of Units (SI).

      That’s why there are plenty of metric units, but not all of them are SI units. :)

       

      Edit: Changed “1892–1895” to “1792–1795”. Lol, whoops.
