RULES:
FFS, just adopt the metric system already. And "lb" is not a force unit. Also don't capitalize unit abbreviations unless named after scientists.
"pound foot" is the most intuitive name for a unit of force imaginable!
How much force? One pound of the foot. Easy!
Red Foreman agrees... "one pound of my foot in your ass"
It's one pound per foot you moron!
/s
Not just any old foot, a square one
It's a derived unit of torque. Pound is already a measure of force.
Of this, you and I, are quite aware.
The Joke, however, is in the air.
Actually pounds are a unit of force
Pounds~newtons
Slugs~ kilograms
Pounds are a unit of money.
lbf
(poundforce) is a misnomer, it’s actually the pressure required to stamp the King’s portrait into a £1 coin. Slightly changes with each monarch – or by a lot whenever they switch to cheaper materials because of devaluation. The frequent redefining of poundforce is now a major consequence of Brexit. /sFairly sure there isn't any money with the king's face on yet. So we're still on the Elizabeth standard for now.
As someone who's all about science and all the things that use metric as it's standard, I understand why us Americans argue for imperial measurements.
We know them.
I can general look at something and relatively tell how big it is based on my experience with the imperial system.
I'm not saying metric isn't better but there's also different languages with some of them being able to express certain emotions or features better than others. Yet you don't see people demanding we all adapt a singular language.
People who grow up almost anywhere else on earth can also tell how big something is based on their experience with metric. That's not something inherently based on the imperial system. The same way you go "oh that's about 3 feet", we go "oh that's about 2 meters".
And of course, switching systems overnight is insane, people are used to imperial, you're right. But at the very least do what Britain did, and have both systems in parallel at the same time, everywhere. And in time, people would get used to metric too.
What I've noticed is that for those using other measurements, intuitively knowing about how long a meter is seems like witchcraft. But for use who are used to metric, it's just "about this much 🫲🫱" or "about this much 🚶".
And you can't learn new things?
They already said they're American lol
We have to exist in a context that resists it. The weatherman will tell you the temperature in Fahrenheit. The road speed limit is listed in mph. You buy milk and gas in gallons.
If anything, Americans who force themselves to use metric in everyday use are working much harder at it than any European.
You should start by adopting metric in anything remotely scientific. Like

Can you imagine having different units across the world for voltage or data? Like a 2¾-lemon battery or a 2 million floppy hard drive. That would be absolutely insane.
There is an awful lot of inconsistency in the imperial system too, like pound being abbreviated

You acknowledge what they really mean is ft lbf right? Usually pronounced foot pounds. It's a common unit of torque in the imperial system. I feel like people are just jumping on the bandwagon. This is coming from a diehard Nm preferrer, we need to choose our battles. How bout we die on the hill of bite force being measured with units of pressure? Like really? Fucking pressure? Utterly meaningless as a unit of comparison between bite strength of animals, since all you need to get a bigger number is SHARPER FUCKING TEETH.
Recommended units for data have been mibibytes (MiB), gibibytes (GiB), etc. for a few years now
They're more accurate because they use powers of two (actually 1024 instead of 1000)
"Accurate" is probably not the correct word anymore. It was when technical limitations dictated power-of-two capacities. Commodore 64 came out with 64 kiB = 2^16^ B of memory, and FAT32 cannot handle file sizes ≥4 GiB (2^32^ B). However, RAM/ROM/Flash chips manufacturers no longer make exclusively powers-of-two capacities, instead opting for (decinal) GB to save 7 % of the cost (and other fake capacity shenanigans). I prefer binary too but the two unit systems can coexist, people just need to label them correctly.
About torque though: If my memory doesn't betray me, one Newtonmeter is 100 grams hooked to a one meter long lever. Is that really different from one pound hanging off a one foot lever? I might be wrong, since I was born metric and have no clue in general.
It's 1 Newton at 1 meter.
As simple as 1 pound at 1 feet to be fair, the bad part is that pound is used as a measure of force as well as of mass. It works on the surface of the earth but not anywhere else.
Pounds are a measure of force, not mass. The imperial unit for mass is Slugs
https://en.wikipedia.org/wiki/Slug_(unit)
I wonder what you’ll get when you ask for 0.02 slugs of ham at a butcher's. Probably nothing but a horrified look.
quick, how many barleycorns in a gunthers chain?
It's confusing, since "pound" is used for both force and mass.
1 lbm is roughly 0.45 kg
1 lbf is the force required to accelerate a 1 slug (32.2 lbm) mass 1 ft/s^2.
I know slugs are just snails without shells, but they don't need to go faster
I don't know what the imperial system standards committee was up to, but I've never met a slug that was 32.2 lbm
You wouldn't know her, she goes to a different school.
It's understandable that you don't understand a measurement system you're not familiar with, but us imperials understand it just fine.
Sure. How much does water in a 1ft × 2ft × 3ft aquarium weigh?
In metric, an equivalent calculation is 30 cm × 60 cm × 90 cm = 3 × 6 × 9 dm^3 = 162 𝑙 ≡ 162 kg of water, and if you're pedantic, the weight is around 1620 N or closer to 1590 N for 𝑔 = 9.8 m·s^-2^. All calculated in my head.
A cubic foot is 7.48 gallons, close enough to 7.5. 1 gallon of water is 8.33 lbs ≈ 25/3.
6 * 7.5 = 45 gallons
45 * 25/3 = 375 lbs -- easy mental math. Sure, the "accurate" answer is 373.87 lbs, but the aquarium probably isn't filled with distilled water, perfectly dimensionally accurate, or filled to that exact capacity.
Oh god this is what we mean
Oh just wait until you see imperial hex screws. In metric you get them in screwdriver size relating to mm. US hex screws are like 16/64 of an inch or 5/16 of an apple. And of course they don't relate to metric at all and you can't use the same tools.
Or fucking AWG. Higher number means smaller diameter wire, and Americans are afraid of decimal or negative numbers so large diameters are 00, 000 etc. The formula is batshit insane
so people just use a lookup table.
Gauge is historically number of passes through gauging machine. With the machine and material in question being different for every single one. We took that and put it to a standard, so it's super messy and makes no sense.
Cope, seethe, mald.
