> and something as simple as dividing a piece of wood in to thirds is unnecessarily imprecise.

Nonsense. It's dead easy. If you have a 120cm piece of wood, one third of it is 40cm.

Now, let's try that in Imperial. 120cm is 3 foot, 11 2/10 inches. How on earth would you go about dividing 3' 11 2/10" into thirds?!

I'll leave you to think about it... ;)

A carpenter in the US is unlikely to measure wood in 10ths of an inch. I make 120cm to be about 47.2441 inches - or almost 3 feet, 11 1/4 inches. Before we quibble over decimal precision, how wide is the saw blade?

Anyone in need of serious wood-butchering arithmetic should find the instructions that should come with an L-shaped carpenter's framing square, and learn what all the various scales can be used for - it's like a slide rule for wooden construction.
