I've noticed new boards quote litres, as in a 120 litre board usually has a "120" emblazoned across it somewhere.
Older boards use something else. For example my 2002 RRD Fireball has "71" across the pads but I can't see the relation between 71 and any other measurement for the board (

71 whats? At first I though inches but that'd make my board about 6 foot long.
P.S. I'm sure it's something obvious and I'm going to go "D'oh!"
