E.g. the British pre-decimal duodecimal currency system?
- riffraff 3y agoBut the British system wasn't really "just" duodecimal either, I recall 20 shilling to a pound and 12 pence to a shilling. I don't recall, but I know about, 4 farthings to a penny. And if Terry Pratchett is to be believed, it was a much worse mess that that.
- dragonwriter 3y ago> E.g. the British pre-decimal duodecimal currency system? It very much was not a duodecimal (powers of 12) system. 1 Farthing (f) 1 half-penny = 2f 1 penny (d) [0] = 4f 1 threepence = 3d = 12f 1 sixpence = 6d = 24f 1 shilling (s) = 12d = 48f 1 crown = 5s = 60d = 240f 1 mark = 13s 4d = 160d = 640f (this was purely a unit of account, and not used after about the 18th C) 1 pound (£) = 20s = 240d = 960f 1 guinea = 1£ 1s = 21s = 260d = 1040f [0] (d) from "denarius", the Roman coin that was the antecedent of the silver penny.
