Nigel PRSONS: 16 ounces to the pound, 14 pounds to the stone
12 inches to the foot, 3 feet to the yard, 22 yards to the chain, 220 yards to the furlong, 8 furlongs one mile.
12 pennies to the shilling, 20 shillings to the pound.
I remember when I started doing a bit of programming in the late 70s, trying to explain Hexadecimal and Octal to my mum.....when I finished my explanation she said (in a broad yorkshire accent):
"Oh, that's nowt then, tha coulda sed that it's nobbut ounces ter pahnds and stoans ter 'underdweights".
I reckon those of us brought up on imperial measurements have a lot less trouble with base-shifting than people brought up in an almost purely base-10 world!
