      How do you measure things in feet? Everyone’s feet are different sizes, that doesn’t seem like a reproducible way to make anything.

        Easy, since Henry the VIII the foot was defined as 12 in. What’s an inch you ask? Well an inch is 3 barleycorns placed side by side. Which 3 barleycorns? That doesn’t matter it’s close enough.
