37 year old American here. I was raised learning both and I can and have built things in both systems. Hell I’ve even mixed them on occasion. I own a metric tape measure and a metric/inch tape measure, and several inch tape measures.
Specifically for woodworking, I vastly prefer working in fractional inches, for a whole stack of reasons but mainly in the wood shop, you find yourself dividing by 2 or 3 way more often than 5 or 10. Working in a dozenal system in powers of 2 makes more sense for that than working in a decimal system in powers of ten. It’s just easier to buy rough lumber at 1 inch thick, use 1/4" of it to mill it flat and parallel so you have 3/4", and now if you need to do a half-lap joint it’ll be 3/8" or a tenon will be 1/4".
Really interesting reply, and thank you for it. I’ve spent time in metric countries, and can, to a limited degree, equate either measurement to the other. Hell, I measure my vodka shots by the ml.
Before I enlisted, I had worked as a laborer putting siding on houses, and had to make cuts in both systems. I naturally default to imperial/avoirdupois, but given that most packaging has metric on it, I can still reference a can of soda as 355 ml. When I vaped, all of my e-juice was sold in mls, too.
Like being a polyglot, learning more than one language has its benefits, but if one has only ever learned one language, the likelihood is high that any other language encountered will seem strange.
Same way you’d take a third of a centimeter: Get out a micrometer and set it to 0.3333, that’ll be pretty close.
The main benefit to the metric system is it’s all base ten. One kilometer is 1000 meters, one kilogram is 1000 grams, you don’t have to memorize that there’s 16 cups in a gallon etc. For a lot of things that works well, the problem is with base ten itself. You run into the same problems with 1000 millimeters in a meter than you do trying to work in thousandths of an inch, it doesn’t divide by 3 particularly well and you get those weird repeating digits.
We kinda did have a base twelve system going, isn’t it weird how we have a special word for twelve in English? There’s 12 hours on a clock face and 12 inches in a foot. And from there, we work in powers of two.
Woodworkers don’t traditionally cut boards to 1 inch or 2 inches thick; they’re rough sawn to that thickness and then dried and milled to 3/4" or 1 1/2". Which are 1/16th or 1/8th of a foot, and both are divisible by 2 and 3 and expressed in a power-of-two fraction. a third of 3/4" is 1/4".
It works very well until someone who doesn’t actually understand it tries to contrive a way to make it not work in the same way their preferred system also doesn’t work.
For many other things, the metric system is easier to deal with, I would much rather do physics in metric than in Imperial (also I’m American, I actually use SAE) but woodworking in a dozenal system is a discipline that is millennia old, the bugs have been very thoroughly shaken out. I would rather build furniture in inches.

That’s what irks me about the “anything other than metric is stupid” crowd. Who needs less tools?
Okay I’ll bite. How do you take a third of an inch, and how is it better than in millimeters?
