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?

    Metric drill bits are measured in mm and hardy anybody needs that much (0.33333… mm/cm) precision. I have a set of metric drill bits in 0.1mm increments and I personally might not ever need greater precision than that. Maybe in some lab environments they need greater precision but I imagine once you’re on that level it would be custom anyway.

      It’s not about precision, it’s because base 10 can’t divide by 3 cleanly. 1/3 is 0;4 in base12 and 0.33333333333… In base 10. All that reflex rounding and sig digit precision stuff takes a lot less of your mind.

      0.33333… is what happens when you try to divide 10 by 3. This is because 10 is such a broken number that 1/3rd (a pretty common fraction) becomes an infinitely repeating decimal. In base12, 1/3rd is 4.0. Metric is broken by design because it’s based on base10. Lets take the lessons learned from the metric system and invent something new, something better, something base12.
