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.
That's an approximate rule of thumb. The definition of a newton is the force required to accelerate 1 kg by 1 m/s². The ocean level gravity of earth just happens to be around 9.82 ≈ 10 m/s², thus a 100g weight feels approx 1N of gravitational force.
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

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.
Yes, but I mean everyone uses it as a measure of mass.
To be fair there exists a mass unit called pound mass, as opposed to pound force.
