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.
Kilogram-force (kgf)
Definition
A kilogram-force (kgf) is a gravitational metric unit of force equal to the force exerted by 1 kilogram of mass under standard gravity. It equals exactly 9.80665 newtons.
History
The kilogram-force was widely used in engineering and commerce before the adoption of the SI system. Many European and Asian countries used kgf as their standard force unit throughout the 19th and early 20th centuries.
Current use
Kilogram-force remains in use in some countries and industries, particularly in China, Russia, and parts of Asia. It appears in specifications for hydraulic presses, engine thrust, and material testing.
