Americans will use anything but the metric system ... unless it's important.
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
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.
For me (in my native language), this means 3g, not 3 kg. :)
The difference is small, but 3g != 3G.
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
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.
You're right. People don't use the system properly, but that's how a lot of people do it is what I was saying. I can see how that would grind your gears (pun somewhat intended) as a machinist, since specs and tolerances are especially important in your line of work as I understand it
What professional area? Because I don't recall ever seeing listings of thousands of mm.
Metal roofing thing (idk how to translate, am not british) are always in mm. We would buy them at like 5 meters long and measure for cutting using mm. https://limarija-sebastijan.hr/krovni-zidni-i-ostali-profilirani-limovi/trapezni-lim/ All the drawings for metal things are in mm. What is not is like diameter of the pipes. The store I linked sells rolls of sheet metal (again don't know how to translate) in cm, but all the other stores sell in mm. https://olx.ba/artikal/19038696/lim-u-rolni/# When you want custom bent stuff (like the metal.. things that go on the sides, or custom gutters) you make a drawing in mm (can't explain, but I'l draw one if you want).
I just said "professional" because the one I replied said it, without saying what profession. Roofing is a profession, and metal roofing stuff doing (again don't know how to translate) is also a profession.
And all the schematics I have seen for metal parts, and in cad software in general, is in mm. Tailoring is also in mm (https://tehnicki.lzmk.hr/clanak/kroj).
Maybe it is a US vs rest of the world thing ? Maybe I'm not expirienced enough to make such sweeping statements.
Again, you put thousands of mm because mixing cm and mm (and m) can lead to mistakes. I even remember cutting wrong because I heard like 2570 instead of 2507 (he's up there measuring, while I'm down cutting).
House blueprints are usually in meters. Window sizes are in cm.
Drug math, keys are for coke.
Concentrate like that is usually sold by the gram. I'm going to assume they phrased it like that so we stoners can immediately visualize it as 3000 1g pots.
Bingo
