This isn’t a real thing, I’ve never heard anyone say “thousands of grams” in my whole life.
When people (and I mean, usually law enforcement) want to inflate the numbers on drug busts, they convert it to “doses” at some unknown conversion rate, or to “market value”. Which kinda makes some sense, because it takes into account the purity level, but still sounds weird.
I have to say that I do this professionally. There is no reason at all to specify tolerances like that. You very much should use at least centimeters with the +/- in decimals. This is the whole point of the metric system. And it aggravates me. We are not stupid as manufacturers. It is very simple division. I am American and have to deal with German and Japanese tolerances quite literally every day. Sure, there are different required ISO tolerances based on millimeters, but as far as prints go? Every company usually specifies their own tolerances. Complying with ISO mostly means that you understand what they require overall. It is my professional opinion that not using the breadth of the metric system is absolutely absurd.
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.
I’ve been a machinist for over 20 years. Just no. You get specs from the customer, and yeah the tolerances are usually in mm. However, listing dimensions in thousands of mm makes no sense. The tolerances are always specified. If it wasn’t for NDA, I could show you a print from Siemens Medical that shows this.
Who says 3000 grams instead of 3 kg anyway.
People do it when they want to make the thing they’re presenting sound more impressive or bigger.

3000 megagigafemtograms!
THREE MILLION milligrams
I’ll have you know I have a whole 27343 cents in my bank account.
pff, rich kid /j
I see millimeters listed by the thousands and hundreds all the time. It really annoys me.
For me (in my native language), this means 3g, not 3 kg. :)
3G? This is what I think of:
The difference is small, but 3g != 3G.
Yeah. I was just making a stupid joke.
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.
