I began using the metric system in science class, and later during a career in archaeology, and I have over the years been looking for metric woodworking tools so I can use it around the house. It is the best thing since sliced bread (actually, I believe it precedes sliced bread....)

I don't have a good feel for the Celsius, but that will change as soon as I have to use it.

I don't understand your point about fractions. English measurement is rife with fractions, but they are non=existent in the metric system. In normal usage, you rarely need to measure anything beyond the nearest millimeter.
