How dare you!

We also measure our drugs that way

Lower numbers look better for that so it's like a cheat code for them.

And distances in track and field events

Hey, we use grams and kilos for...other things too.

It is funny how we're schizophrenic about it, though. Things will go from grams to ounces and then to kilos...or, so I've heard.

Edit: American cars are also kind of schizo like that, or at least they used to be. The engine and everything attached to it was metric and everything else was SAE. Fun times.

[–] bizzle@lemmy.world 14 points 1 day ago (1 children)

Yeah but now I know that there are 28.5 grams in an ounce

[–] doingthestuff@lemy.lol 8 points 1 day ago

28.35. And don't expect more than 28. 3.5x8=28, and since every bag can't be exact, that's why lots of plugs have a bag or two that are just under.

[–] ghostlychonk@lemm.ee 8 points 1 day ago (5 children)

That's because a lot of American cars were/are using engines made by European or Asian subsidiaries while most of the rest of the car is produced domestically.

[–] Kickforce@lemmy.wtf 3 points 21 hours ago (3 children)

Sounds like they wanted engines that work.

The imperial system makes you a worse shot. Everybody in American stories misses by inches. In European stories, they miss by millimeters. It's quite the difference: 25 times worse.

[–] Soggy@lemmy.world 5 points 21 hours ago

It's not a real fish tale if people are measuring in standard units instead of "c-hairs" or "gnat bollocks" anyway.

[–] LovableSidekick@lemmy.world 32 points 23 hours ago* (last edited 23 hours ago) (2 children)

Longtime woodworker here (American). Fractions of an inch have always been a pain. Finished lumber like 2x4s and 1x12s have never in my lifetime been the size they're known as, but that's a matter of subtracting halves and quarters of an inch and everybody was used to it. Then maybe 20 years ago (no need to correct me, it really doesn't matter) companies decided that instead of making plywood the thickness they said it was, they would subtract 1/32th of an inch, because hey less wood means more profits! So for example a sheet of so-called 3/4" plywood is only 23/32" thick. Similarly with half-inch, etc. This means a slot cut with a 3/4" router bit, which used to fit a 3/4" thick shelf, is just slightly loose now, and if you are stacking multiple thicknesses the slight inaccuracies compound themselves. What the Actual Fuck. I have a metric tape measure, which makes some figuring easier, but inches and fractions of inches don't convert to exact mm. The imperial system is a shit show.

[–] ChickenLadyLovesLife@lemmy.world 8 points 18 hours ago (2 children)

I recently bought a house that was built in 1942 and I've been renovating it. I tore down one of the interior walls and reused the studs (which incidentally were completely straight and free of knots, unlike any modern 2x4 I've ever seen) to build a new wall. When I put the wall in place it didn't quite fit and when I measured I realized it was 1/2" too tall. I don't normally make measurement errors of that magnitude and it took me a while to figure out that the studs I was reusing were not 3.5"x1.5" like modern 2x4s but were actually 3.75"x1.75" (so the base plate and head plate being thicker than I thought was producing the problem). Apparently the transition from real 2x4 to BS 2x4 dimensions was gradual, who knew.

One other weird thing was how the interior walls and ceilings were covered. I've worked on a lot of 19th century houses with lathe and plaster and of course I've worked with modern sheet rock. This 1942 house was in a transitional phase that used 16"x16" blocks of 1" thick rough plaster that were nailed to the studs, and then finish plasterers came in and put a smooth plaster coat over these rough blocks. I've never seen anything like that before, and removing these rough plaster blocks was a monstrous bitch - each one weighs as much as a solid rock of those dimensions and I have no idea how a few nails were holding them up on the ceiling joists.

Also found a hat in the attic from 1942. I like to imagine some young worker wondering for the rest of his life where he put his favorite hat.

use cabinet grade instead of construction grade for your plywood. The good shit will actually be what it says it is.

Oh no, it's worse than that... we use the metric system to measure the customary system...

The Mendenhall Order marked a decision to change the fundamental standards of length and mass of the United States from the customary standards based on those of England to metric standards. It was issued on April 5, 1893, by Thomas Corwin Mendenhall.
[...]
Mendenhall ordered that the standards used for the most accurate length and mass comparison change from certain yard and pound objects to certain meter and kilogram objects, but did not require anyone outside of the Office of Weights and Measures to change from the customary units to the metric system.

https://en.wikipedia.org/wiki/Mendenhall_Order

Technically every unit in the US customary measurement system is just a weird conversion factor of an equivalent metric unit. At this point 1 yard was defined as 3600/3937 meter, which means 1 inch = 2.54000508 cm. By 1959 everyone finally agreed that this was stupid and redefined it as 1 yard = 0.9144 m (1 inch = 2.54 cm).

All measurements in the US are based on standard reference objects provided by BIPM.

Most of us know what two liters of carbonated sugar water looks like.

Hey, that's flavored carbonated sugar water if you don't mind.

[–] JPSound@lemmy.world 15 points 10 hours ago

M'erican here. My workshop is 100% metric. I do far too much measuring, designing and planning to fuck around with inches, feet and football fields. Motherfuck the imperial system. America has been robbed of the superior until of measurement. Every last bit of my work is in millimeters and it will be that way until I die in a horrible firey accident in my shop because beer and dangerous power tools are just too much fun when taken together.

[–] HootinNHollerin@lemmy.dbzer0.com 14 points 1 day ago (1 children)

Every US company I’ve (engineer) worked for has been a metric company

[–] jawa22@lemmy.blahaj.zone 13 points 1 day ago (2 children)

I (machinist) have only seen a few large US firms or companies send me a metric print. Different worlds, I guess.

.223: Proper American rifle round.

5.56: Communist European rifle round.

[–] doingthestuff@lemy.lol 5 points 1 day ago (1 children)

5.56 puts out slightly higher pressures. I used to have a bolt action .223 rifle that wasn't rated for 5.56. I sold it to an old guy in the country who was going to use it to kill coyotes stalking his chickens and small livestock.

cops: "9mm is too weak! we need something with 'stopping power!"

gun people: "ok here's 10mm"

cops: "too much recoil!"

gun people: "ok here's .40 s&w"

cops: "u no wat, we're just gonna stick with 9mm"

This is why i use the amertric system

It 318 kft not 60 mi or 100 km. That avalanche was 1 decaempire State building in volume. 1 mi is actually 2.28 kft.

And the only time they use the proper date format is their national holiday.

[–] Septimaeus@infosec.pub 5 points 6 hours ago

If you mean dd-mm-yyyy instead of mm-dd-yyyy, I’d agree it’s superior. That said, other countries have us both with their fully ISO compliant yyyy-mm-dd standard.

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

[–] deranger@sh.itjust.works 3 points 1 day ago* (last edited 1 day ago) (2 children)

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.

[–] MightBeAlpharius@lemmy.world 3 points 1 day ago* (last edited 1 day ago) (1 children)

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

[–] exasperation@lemmy.dbzer0.com 8 points 1 day ago (1 children)

That still makes no sense. Is the commenter surprised to learn that a 0.223 inch caliber is approximately 0.223 inches? That a .45 inch caliber is about .45 inches? Yes, that's how units work.

[–] evasive_chimpanzee@lemmy.world 4 points 1 day ago* (last edited 20 hours ago) (2 children)

But you don't call it "point four five caliber" you call it "forty five caliber". Similar is 7.62 mm AKA "thirty caliber". It's reasonable that someone wouldn't know that it's literally just hundredths of inches.

Shotgun gauge is wonky, so it's not a given that the number would just be a diameter in units they are familiar with. "Grains" are also a meaningless unit to most people.

[–] baldingpudenda@lemmy.world 4 points 22 hours ago

What do you mean? its 7000 grains in a pound. 27ish grains to a dram, 16 drams to an ounce, and 16 ounces to a pound. Pretty straight forward.

Also dont confuse an ounce(oz) and a fluid ounce(fl oz). That's 8 fluid drams to a fl oz, 16 fl oz to a pint, 2 pints to a quart, and 4 quarts to a fucking gallon cause it makes sense. Obviously, 63 gallons to the hogshead.
