    Woodworking, sure. You have a piece of wood 2’ 5 5/8“ long that you need to cut into quarters. Can you calculate that in your head? Metric is SOOOO much easier.

      here’s how i did: 2’/4=6", 5 5/8"/4=1 13/32, so it’s 7 13/32"

      smart to pick a prime numerator!

        Alternatively, the same measurement is 752.5mm / 4 = 188.1mm, to a practical number of significant figures. No convertions between feet and inches (or ridiculous fractions of inches), and only one calculation.
