A system of ten when you've got a ten based numerical system makes sense. You can divide ten by any of the numbers.... just go into decimals. Man up, man!

I thought the ha'pnees and farthings and all was a lot of fun when I was there, though. And the weirdness in big heavy coins with small value, the itty bitty sixpence,etc.

Someday we'll look back on foot-pounds feet and miles with the same sense of disbelief.
