    I’m on the record as genuinely preferring fractional inches to decimal units in the wood shop because it’s inherently a fractional task. 12 inches in a foot; keep dividing that by two and you get 6", 3", 1 1/2", 3/4", 3/8" and so on. 3/4" is the basic unit of woodworking. I have to divide by two and three quite a lot in the wood shop, so dividing 3/4" by three is 1/4" Easy.

    Did this today: I had a 1 1/2" thick board, and had to cut a 1/2" groove down the center of that board. 1 1/2 divided by three is 1/2" so I chucked a 1/2" spiral bit in my router, set the fence 1/2" from the bit and the grooves are perfectly centered. Easy.

    I’m not against the metric system, I learned chemistry and physics in metric, I own a set of metric wrenches. My measuring cups are graduated in fractional cups and milliliters, my kitchen scale measures in ounces, pounds and grams. But I build furniture in fractional inches and I learned to fly a plane in feet, pounds, gallons and nautical miles, and I’m damn good at both.
