Sackers has a piece on imperial versus metric and argues:
The old pound – 20 shillings of 12 pence each, making 240 pence – can be divided in 18 ways: by 2,3,4,5,6,8,10,12,15,16,20,24,30,40,48,60,80 and 120.
Using halfpennies, you could also split the pound by 32, 96 and 160; and with farthings (quarter pennies, still used until 1960) you could further divide £1 by 64 and 192.
So the old way functioned 3 times better than the new one, technically speaking.
Anyway, it does drive me batty having to convert 4864mm to feet and inches to get a reasonable system which one can build by and then, when ordering, having to convert it all back to metric again.
What an infernal pain in the nether regions.
