Pound-force (lbf)
Definition
A pound-force (lbf) is an imperial unit of force equal to the gravitational force on a mass of one avoirdupois pound under standard gravity. It equals approximately 4.44822 newtons.
History
The pound-force evolved from the English system of weights and measures. It became formalized as distinct from the pound-mass in the 19th century as engineers needed to differentiate between mass and force in calculations.
Current use
Pound-force is widely used in the United States and United Kingdom in engineering, aerospace, and manufacturing. Jet engine thrust, structural loads, and material strengths are frequently specified in lbf.
Gram-force (gf)
Definition
A gram-force (gf) is a unit of force equal to the gravitational force exerted on a mass of 1 gram under standard gravity (9.80665 m/s²). It equals approximately 0.00981 newtons.
History
The gram-force originated from the gravitational metric system where weight units were defined by the force of gravity on mass units. It was commonly used before the SI system formalized the newton as the standard.
Current use
Gram-force is still used in some specialized fields such as textile tension testing, spring force measurement, and precision weighing applications where small gravitational forces are referenced.
