COMMENTS
The pound-force is the product of one avoirdupois pound (exactly 0.45359237 kg) and the standard acceleration due to gravity, 9.80665 m/s^2. Hence, a pound-force is equal to exactly 4.4482216152605 N.
This unit of force is used in the system of English Engineering Units.
EXAMPLE
1 lbf = (0.45359237 kg) * (9.80665 m/s^2) = 4.4482216152605 N.
