I'll chime in real quick here! The problem with the metric system is
that it's based on 10. Most of the metric proponents say that a decimal
system is superior because it makes floating point calculations easier.
What I think they overlook is that designers don't really do that much
floating point math. What designers want is to be able to say, "Let's
divide this thing up into thirds (or quarters)". A measurement system
based on 12 is much easier to use because it's evenly divisible in more
ways than 10.

P.S. And another thing, what about time? Anyone want to put in an 8 hour
day when the whole day is only 10 hours ;), I guess they could make it
up to me with a four day weekend in the new 10 day week...
