    Nor obvious, but based on physical principals and highly reproducible. BTW, what’s the official definition of an inch?

      Roughly the length of the last segment of my thumb. Which is roughly 1/12th the length of my foot. Which is roughly 1/3 of my stride.

      Things I don’t need a vacuum and instruments that can measure the speed of light to reproduce.

      A mole is a very useful unit of measurement in chemistry, but much less so in baking.

        You want to know an obvious meter metric? Roughly slightly more than half my body in length. Two can play the stupid game.
