You can rest assured that the laws of physics don’t care whether you measure them in inches or cm.

“Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4 mm.”

The inch you like so much is now defined as a derivative of an SI unit.

That's what I said. The units don't matter as long as they're standardized. Europe's problem is that its a continent filled with various tribes who all speak their own language and uses their own units and whatever as a point of tribal pride. Europe will stay losing as long as they remain tribal and dividided. And this problem only expands over time, as of the present moment Europe is completely propped up by America. They can't defend themselves or build their own things that work.

There's the definition of the inch that you gave (the meaningless "International Yard", which sounds like the spawn of some European bureaucrat) and there's the true definition of the inch in the context of American engineering. The inch = 1 inch. It's defined to itself, total unity, 1, no decimals. That's what standardization means.

The American Inch is not exactly 25.4 mm. Its close but not quite. That's what I've been saying about the robust American engineering network, but I get the idea that you have no formal training in metrology and have no idea what I'm talking about

Here, talk to my chatGPT for a second:

You have no idea what you're talking about and ChatGPT is far from the Supreme arbiter of truth, it's taking the international definition out of context

Talk all you want. But still 1 inch = 25.4mm. Exactly.

If you have a ruler that disagrees with this, well… you’ve got yourself a shitty ruler.

Sorry for interrupting your conversation, but

US officials say assistance to Ukraine's offensive operations has scaled back, but defensive help continues

The US is still sharing intelligence with Ukraine that can help its troops defend themselves, but has “scaled back” sharing any intelligence that Ukrainian forces could use for offensive targeting of Russian troops, according to two US defense officials.

The US does not want to be seen as actively helping the Ukraine strike Russia, which is also why military aid deliveries were paused earlier this week, the officials said. But the US is also not going to withhold information that could help Ukraine protect itself, the officials said.

Elon Musk’s satellite internet service Starlink, the main satellite system that the Ukrainians rely on to communicate on the battlefield, is still active, the officials said.

It's like everything I said went in one ear and out the other.

On the scale of visible light, the difference cannot be distinguished. Hence why I mentioned ultra-precision engineering earlier

No. It’s like you just are incapable of admitting you were wrong. You do this a lot on these forums, I saw.

1 inch = 25.4 mm

That’s the definition. Not some 25.4 mm + very elusive epsilon your professor told you about and you may or may not have understood him well.

I understand a different point. That if a rocket was designed using half-inch steel and screws 3/4 of an inch in diameter and some country wants to copy it, instead of building from the ground-up, then it needs a source of half-inch steel and 3/4 inch screws. Which it might not have in large quantities if it’s industry is mostly producing 1.5mm steel and 2cm screws. I’ve heard that Russians once tried reverse engineering a fallen a spy-plane during cold war, but using parts with different sizes for this reason and - surprise, surprise - it didn’t fly. It’s really simple.

But there are so many other reasons why Europe doesn’t have competitive aero-space program… That access to a 3/4 inch screws is very far down in the hierarchy.

It is you who refuses to admit that you have no idea what you're talking about
