In the last 55 years, how many metric-using countries have put footprints on the moon?
5.56 = .22 cal
7.62 = .308
9mm = .38
45acp = has no commie metric equivalent.
*heh*
Yep, an essential list
with a fun quibble for you 9mm nit-pickers:
9mm = 0.354in,
38spl bullet is 0.357in dia,
38spl is a trade name (like 45acp), and
357mag is an extended 38spl.
They’re all 9mms
(What? Nope, quitting there. Not gonna do the short 9s: 380acp, 9mm kurz, etc.)
Geez, Doug, why not?
…and a 50 Cal is 12.3mm and will Make Your Day.
We had metric units foisted upon us in engineering school in ~1965. The arithmetic is simple enough, but how big, how fast, how heavy in every day examples was and still is pretty much lost to me. But – while somebody telling me an object weighs 145 grams means nothing to me without mental gymnastics in terms of mental image and heft, but tell me it weighs about 5 oz – bingo – it’s a baseball.
We had a revolution 248 years ago, and we still don’t want no metric rulers.
Calculate using metric. Then convert the results to English units for a sanity check.
No, that 22LR bullet did not drop 3.6 miles at 100 yards.
In school I was the only one to get one problem correct.
We all made the same mistake, not taking a square root at the end.
I was the only one to convert m/s into MPH and realize a roller coaster isn’t going to go 6400mph.
I thought our biggest fear, the biggest danger to our carriers was Chinese hypersonic roller coasters.
If we go metric (and, technically speaking, we have) it’ll make it easier for the Chinese to copy our weapons systems…
Just sayin’
Besides,
Liberty son, Liberty.
Just remember to use the right units for the job.
