Every professional that deals with stuff that needs around 1mm precision uses mm. Metal roofing, gutters, any machining, etc. It is to prevent ambiguity. I used to build roofs and for like wooden beams we used meters and cm, but that was because a couple mm here and there rarely ever mattered. All in all using mm is usually the best choice.
Sure. I’m not a professional machinist. I have worked on roofs and all sheet metal things are in mm. I have even worked for a company that makes those metal things and as a customer for another one. I also was by far the best at technical drawing in school, not to brag. And all the schematics for things I have seen are in mm, for example https://www.iclarified.com/images/news/48931/228250/228250-1280.png . Disclaimer, all the schematics that are not in, ugh, inches (or architecture).
Sure, if I made something for someone they can give me dimensions in Smoots for all I care. But I would transform it into mm, and would never buy tools that don’t use mm.
For context, I am not in an english speaking country nor Myanmar.
Edit: Actually I have seen house schematics in mm as well. I thing they now give out in m, but use mm internally (depending on architecture firm).
When I asked the boss, who has been in the business for a couple generations, why it says here 4000 instead of 4m, he said what I am telling you. So you don’t mix up measurements.

A lot of times it’s based on precision. Kinda makes sense to say 1,000 mm if the spec is +/- a mm or 2 imo

What professional area? Because I don’t recall ever seeing listings of thousands of mm.
For me (in my native language), this means 3g, not 3 kg. :)

The difference is small, but 3g != 3G.
