## Main Question or Discussion Point

Ok i am too confused with these american units. I have a couple of questions about them

Q1) Is lbf a force. Is lbm a mass. If yh does it mean 1 lbm = 32.174 lbf.

Q2) Is lb equal to lbm or lbf.

Q3) Is lbs equal to lb or lbm or lbf.

Q4) Lets say 1 lbm = 32.174 lbf. and from many sources i found that 1 lbf = 4.44822 N and 1 lbm = 0.45359 Kg.

So lets try this.

1 lbm ---> 0.45359 kg

0.45359*g = 0.45359*(9.81) = 4.4497 N

then using conversion 4.4497 N = 1 lbf !!!

Wow we proved 1 lbf = 1 lbm. ??!! Does it mean 1 lbm = 1 lbf and not 1 lbm = 32.174 lbf. ??

What is going on here.Is the mass and force same in the American system.
