Bro 10mm rounds exist
.40 S&W and 10mm auto are both 10mm rounds!
.40 S&W and 10mm auto are both 10mm rounds!
I don’t trust you, stranger number man! And the above… well that just proves there’s a conspiracy!

Here's the funny thing. A 9mm is closer to a cm. The rim is 9.96mm.
Can US people imagine their size in a whim?
Probably not. It's a fairly rare round outside of fallout.

Centimeters are on the American ruler...
We also put inches on ours, yet not a single soul has ever used that side. I think it's only to constantly remind us we are superior ;)

Yeah Stormy said it was only a centimeter
The only thing on a real American ruler is red white and blue .
I thought he is orange
His preferred title is typically translated as "leader" not "ruler" that's got monarchist elements that they can't quite make stick yet

I always thought it was cheeky that a lot of pistols in Fallout take 10mm ammo.
Tbf 10mm Auto is a real caliber (that the FBI tried to use but "it hurted their wrists" so .40SW was invented.)

SW stands for Soft Wankers.
LOL it might as well since their weak ass wrists couldn't take it!
(For those who are wondering it's of course actually "Smith & Wesson.")

As an American mechanical engineer, i do more unit conversions between metric and standard/ uscs than many people do in a lifetime
Hell just today I designed a custom spring in both as i need it asap and have to settle for the inch
We occasionally get engineering diagrams from clients in the US and they're always going on about screws that are 2/3 of an inch long. It's not just that you're not using metric you're using a weird fraction and not a decimal.
It's super confusing when you get into high precision stuff because then they start going on about 128th of an inch. Just tell me how big you want it, stop telling me what fraction of a different measurement it is. Surely there is something below inch that you could use. I still wouldn't know what you were talking about, but at least it would look less stupid when you wrote it down.

Canadian engineer here. Although we use the metric system in principle, in reality we use feet and inches for everything. There are lots of benefits to using base 12 for measurements.
The number 12 has six factors, which are 1, 2, 3, 4, 6, and 12. It is the smallest number to have six factors, the largest number to have at least half of the numbers below it as divisors, and is only slightly larger than 10. (The numbers 18 and 20 also have six factors but are much larger.) Ten, in contrast, only has four factors, which are 1, 2, 5, and 10.
I get the Europeans hate it though because only the people who live near Chernobyl can count to 12 on their fingers.
The thing is, we just use whole numbers. If you get under 1, then you move down by one SI prefix et voilà, you have whole numbers again
I've never thought of counting on fingers as a good reason for using it for units. But since our numeric system is base 10 (likely because of having 10 fingers indeed), it's easier to have our unit systems as base 10 too. If we all learned to think in base 12 from ground up, having base 12 units would make a lot more sense too
Btw you can count to 12 on your fingers with one hand. Starting from the end of the index finger tap each segment of the "remaining" four fingers with your thumb.
I heard someone claim that's how Babylonians invented and used the base 12 system in the first place.
The thing is that outside of North America people aren't terrified to death of decimals. We actually use them and find the process simple. So those factors of yours are completely irrelevant to us.

I know it'll never happen but I'm still camp duodecimal, all the way.

I wonder, when they get a grown-up president again, will they finally also begin to move to the 21st century?
You’re being way too optimistic
Again???
A system of measurement in which something like 15/16 of an inch is seen as a sensible way to measure a small distance. Not much else to say.

The Americans could've changed to the metric system if they could afford it. However, changing a country's systems of measurement is a mammoth project of enormous complexity and cost, so I guess no politician want to make space for that in the budget when there are other things to take care of.
Maybe people will forget about the epstein files if he tries changing to metric
Genuinely, that would be the funniest reason... Maybe we should be inundating Trump with recommendations like this to 'fix' his approval ratings.
... and then hang him anyways after the next Nuremberg trials.

Don't be silly, you lot are going to gold plate his pension and that of his family for decades to come. LOL next Nuremberg trials. Who are you kidding?

People just don't really care enough to. And we already use the metric system in science, engineering, medicine, aerospace, military, and any science class in high school or higher. So what if our road signs and cookbooks are in imperial units.

5 cm is 1.9685 inches, which is about weeee big…. 🤏
Or one LLAP 🖖
