Each and every time this comes up. I say that I am familiar with the metric system and use it for quite a few things, but I specifically prefer woodworking in fractional inches because working in base 12 and power-of-two fractions is closer to the tasks I need to perform in the wood shop than base ten decimal math does.

I give real-world examples like "divide 19mm, a commonly used stock thickness, by three to make a tenon, you get something point 3333 repeating of course" and they 1. downvote and 2. Invent sizes that we don't conventionally mill stock to thinking they found a "gotcha." "Well what's 2 inches divided by three?" we don't mill stock to 2 inches thick, we'd use 1 1/2", a third of which is 1/2". Y'all actually do use 19mm.

But Americans use inch fractions so inch fractions must be dumb and bad, right?

Yeah it really only matters what you are comfortable with, if you get units you aren't comfortable with then it gets confusing. I almost feel like metric folk don't realize that the USA is like 50 EU states in size, and this disconnect causes them some rage at seeing imperial units. At the human level I still can't comprehend Celsius, mostly cuz those numbers have meanings in fahrenheit, sure makes for some cognitive dissonance to heard 35 degrees thinking you would need snow gear to hearing it's unbearably hot.

I would not mind if americans used whatever. As long as anything exported from america always!! used metric. As it is now we need 2 complete sets of nuts and bolts, pipes and fittings, tools and gizmos, csbles and connectors. Just imagine the space we could save in our shops and storages if we could /2 the requires spare part storage. Not to mention the time and frustration avoided when doing basically anything on almost anything.

Nah, what're you talking about?

Case in point: whose foot?
