Not quite true. My grandfather was a carpenter specialised on furniture and windows. He would say everything off 0.1 mm or more is that bad that you have to redo the piece. And he was right: A 0.1 mm gap in a joint is an ugly and very visible gash in your work.
If the error is less than 0.1 mm it is still not good work, but you can hide it with glue and sawdust. It is still rather easy to detect if you run your fingernail over it, but at least it is not that visible anymore.
He used big machines and hand tools, but no milling, CNC or other computer controlled machines. So decimals in millimetres are definitely useful outside of milling and the precision is achievable - even for me, who isnt a professional woodworker.
Going into decimal mm really isn’t necessary for anything. No one can be that precise (except milling).

The person before me did it, and they use commas instead of decimal points, so I assumed it was a standard car measurement in Europe.
3,635 mm is not 3.635 mm. If you want it’s 3.635 meters.
I had to double check after I read your comment. Another benefit of metric. Even when you’re wrong there’s a good chance you’re right.
Whoops.
Depends on the system and where you live. In hand writing, i would use 3,635 mm for decimals. However, on computer 3’635 mm to write 3.635 m.
Personally, I like the high comma as a thousands separator as it removes possibilities to misread the number. But not everyone will agree.
