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.
