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.
