I love woodworking, and many years ago when I first trying to get some tools together, with very, very little money to my name, a friend of a friend gifted me a bunch of stuff, but it was all metric. My speed square was the only non metric tool I had (I’m in the States). Took me forever to find a metric speed square I could afford. Lol. It suuuuuucked doing the conversion for everything. Lol
