How it's calculated
N = lbf × 4.448222
lbf = pounds-force, N = newtons. 1 lbf = 4.448222 N. Reverse: lbf = N × 0.224809.

Common questions
What is the difference between pound-force and pound-mass?
Pound-mass measures an amount of matter, while pound-force measures the weight that mass exerts in standard gravity. One pound-mass weighs one pound-force on Earth.
How many newtons is one pound of force?
One pound-force equals exactly 4.4482216 newtons, so 10 lbf is about 44.5 N.
