A kilogram-force (kgf) is a unit of force equal to the force exerted on one kilogram of mass by standard gravity ( gn ), a standardized value representing the average magnitude of gravitational acceleration on Earth's surface.[1] Therefore, one kilogram-force is by definition equal to 9.80665 newtons.[2]
The kilogram-force was not very well defined until the 3rd General Conference on Weights and Measures (Conférence Générale des Poids et Mesures, CGPM) defined the standard gravity,gn, to be 9.80665 m/s2. Although it was once widely used, it has never been part of the International System of Units (SI) introduced in 1960 by the
