Took me a while to realize that Caliber is roughly inch/100. Once I did I no longer needed to memorize them.

I don’t understand. A 5.56mm round has a .223 bullet. .223 is the caliber and is in inches already, no math required. .223 / 100 =0.00223 which isn’t particularly useful.
Their math was flawed, but I'm not really sure how to explain the math part better. I get what they were going for, though.
It's closer to decimal divisions of an inch, so a .223 caliber bullet would be a hair shy of a quarter of an inch (.25) wide.
Edit: just realized you had the second part of that already

And the druggies. Somehow, they had no trouble switching to metric.
Also wetsuits…? 🤷♀️
they would freak out if they have to measure temperature in kelvins, even celcius freaks americans out.
We all use metric. We need to just rip the bandaid off.
Hey, that's a win. I'll take it.
Priorities.
It's like that because everyone else measures them that way, and capitalism. It's not even because it's a better system, it's because money.
9mm Parabellum was designed by Austrian George Luger 10mm Auto was designed by FFV Norma AB of Sweden 5.56 NATO was developed in Belgium by FN Herstal, as was 5.7mm 7.62×39mm was developed by the Soviets
These European cartridges all use metric measurements
.223 Remington, .308 Winchester, .30-06 Springfield, .40 Smith & Wesson, .22lr, .357 Smith & Wesson Magnum, .44 Remington Magnum are all American made cartridges that use decimals of Imperial measurements Original designer’s name gets includes because, well, capitalism lol
I think one of the few exceptions might be 6.5mm Creedmoor, developed by Hornady
