Another one is the time & motion studies folks, they work in decimal minutes.

3mm is very good IMO. Believe it or not many concreting contractors standard tolerance is +/- 15mm on poured slabs.

Generally I work in mm for work, but happy to work in inches.
Sometimes I'll use inches if I'm marking the middle of something and the inches are quicker to divide up mentally, I can use fractions without much thought.
Did this last week on something I was making at home. Half of something was 3¼" or whatever, so went to put a mark there... then I had to do a double take...took me a moment to work out where ¼ marks were.
I remembered then why I generally don't buy tools from discount european supermarkets. First time in many years I've broken my own rule, and I ended up with that junk.

That was a poured slab as it goes.
Seen some shockers over the years
Extension last year was over 40mm low at the furthest point and that was screed over a block and beam.

Even my kids give me measurements in mm these days.
Gave my eldest my drawing board the other day. He's gonna try and draw a scale floor plan of the ground floor here

If you really want to confuse, just start using mils.

I find Imperial far easier to use. I do work in both and if something I’m cutting happens to be 39 3/4 one way and 525mm the other, so what. I had to use a metric only tape the other day, failed and went and got an imperial metric one.
If they did a chains, furlongs fathoms and cubits one, I’d probably use that too' I find it keeps my old brain sharp.
97” and 3mm makes perfect sense to me. But then mental arithmetic and multiplication tables were drummed into us as kids. Now I find youngsters reach for a calculator for the smallest sum. Someone wanted a percentage the other day and I reeled it straight off. They all got their iPhones out to check I was correct. The worst one recently was at a till when I had a BOGOF item at 87p. She was trying to work out how much each one was. I said it doesn’t matter! It’s free! Ended up calling a supervisor. They do my head in.

You'd need a bigger hammer if you swapped thou for 0.01 rather than 0.001 thoAt work if you want to make tolerences sound better make sure to use thou not 0.01
I'm currently in the land of not as free as they thought they were, waving a metric tape and giving English dimensions
Lunch time today - in a chick-fil-a - came to $11.04, so I chucked $21.05 at her, keep the penny change . . . that confused her . . . called her supervisor . . . confused her too . . . gave me the $1.05 back, gave me the change from the $20 that the till told her . . . so I still have funny notes to get rid of . . .
