    well yeah, because 1/8" is 3.175mm

    1/3 of a mm is a distance between 1/64" and 1/128"

    mechanical pencil lead is only about 0.4mm

    I still don’t see how a calculator helps though.

    don’t ask me ask the person who posed the “what’s a third of 9.5mm” question

      Usually when I’m making a precise line, I’ll put an edge on the pencil lead so it will make a mark thinner than its diameter.

      I seem to remember you as the one who brought up calculators, but I’m open to being mistaken.

        even if you’re in a situation where it’s somehow possible to manually draw 1/3 of a mm to any accuracy, 1/3 scale draft rulers still exist for metric, so it’s equivalent

        because as soon as you have access to a calculator, “off the top of your head” is an irrelevance
