I always thought it was cheeky that a lot of pistols in Fallout take 10mm ammo.

I wonder, when they get a grown-up president again, will they finally also begin to move to the 21st century?
Again???
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 ;)
Screens are measured in inches
Is Zoll and Inch the same thing?
Were taught to think in inches at fashion design school.
Most people by far don't attend fashion design school.
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
You can't rule a country off a cliff, only lead.
Why don't they just round that guy's votes up to 60?
You’ve unlocked: the number 10
Bro 10mm rounds exist
Here's the funny thing. A 9mm is closer to a cm. The rim is 9.96mm.
.40 S&W and 10mm auto are both 10mm rounds!
I wonder, did you feel like "cool" writing this comment? It's an honest question. Sorry in advance if it sounds like a jerk question.

I don’t trust you, stranger number man! And the above… well that just proves there’s a conspiracy!

Can US people imagine their size in a whim?
We can’t imagine 9mm on a whim either.
Probably not. It's a fairly rare round outside of fallout.
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
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.
Sure, but does my 5/32" drill hit go left or right of the 7/64" on my drill bit sorting block?...
5/32 is 10/64, maybe you can figure it out from there.

12 is better than 10, I'll give you that. But 100 is better than 144, and 1000 is way better than 1728.
And that doesn't even get to 0.1 versus 1/12, or 0.01 versus 1/144.
So 12 might be a better standalone number, but it's a terrible base to work in.
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.
If you look at your hand when it is wide open and palm up you can use the tip of your thumb to touch any of the 12 (four fingers each with three) sections of your fingers. Counting in 12 might be very intuitive for early humans - or might not. Who knows.
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.
I know it'll never happen but I'm still camp duodecimal, all the way.
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.
A thou is a milliinch
Every company ive ever worked for has been metric. All American companies. But i do machines and instruments.
I deal with standard / uscs units because suppliers still do
Isn't the UK just as bad? You have a zoo of units over there. Stone, miles, pints, etc.
The US is the only country that uses non-metric units when doing anything industrial though. I might buy a pint of milk but I'm not going to measure in anything but metres and centimetres.
