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.
Kilonewtons (kN)
Definition
A kilonewton (kN) is a metric unit of force equal to 1,000 newtons. It is used to express large forces in engineering and construction.
History
The kilonewton naturally followed the SI prefix system applied to the newton. It became widely used in the 20th century as civil and structural engineering required concise notation for large forces.
Current use
Kilonewtons are commonly used in structural engineering for expressing loads on bridges, buildings, and foundations. Vehicle weight capacities, crane ratings, and tensile strengths are often specified in kN.
