As well as 3, 8, 14, 16 (feet/yard, pints/gallon, lbs/stone, ounces/lb) 
and probably many others. But it's was more modulo arithmetic rather 
than using bases, as the numbers of each unit are still expressed in 
decimal.

Many of these are mixed 'base' as well, another difference from numbers 
that genuinely use other bases where the base doesn't usually change 2 
or 3 times within the number.
