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.
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.
