That’s a fun problem, if you enjoy recreational mathematics. However, if you need to deal with this nonsense on a daily basis, it get’s old pretty fast.

Oh, yeah, the pounds, shillings and pence system was just epic. One pound (money, not weight) is 20 shillings (because why not), and one shilling is 12 pence (just for maximum confusion). In order to use measurements or money, you need to memorize a bunch of arbitrary conversion factors, which was obviously loved by everyone.
