One thing in favor of the english system, to me anyway...

Measurement of length (the foot) is based on 12 rather than 10.

This is bad in many events, but it can make some situations easier as 12 is evenly divisible into thirds and fourths.

1/4 of 12 is 3
1/3 of 12 is 4

but with the metric system:

1/4 of 10 is 2.5
1/3 of 10 is 3.3333333333333333333 (repeating to infinity)

not that all of that is a big deal, but as far as some things go & doing the math in your head english can be easier...

Overall though, I wish the world would standardize on something, apparently the metric system. As a VW fanatic I only have metric tools, so i've already standardized ;)

For bolts & nuts metric is far superior, having gotten used to the logical sizing of wrenches, i'll never miss having tried to use an 11/32 wrench and trying to figure which size in my disorganized toolbox would be the next bigger.

P.S. most metric & english fasteners have close equivalents. I can use a 13mm wrench on a 1/2 hex head, but the two can't thread into each other etc.
