Convert pound-force to kilogram-force
pound-force
Definition: The pound-force (symbol: lbf) is a unit of force used in the English Engineering System and the British Gravitational System. It is defined as the gravitational force exerted on a mass of one avoirdupois pound under the condition of standard gravity (9.80665 m/s2). Under this definition, with mass in terms of slugs, one pound-force is equal to 1 slug·foot/second2.
History/origin: The pound-force is part of the foot-pound-second (FPS) system of units. Until 1901, when the General Conference of Weights and Measures adopted a standard acceleration due to gravity of 9.80665 m/s2, the pound-force was not precisely defined.
Current use: After the adoption of the International System of Units (SI), the newton, an SI derived unit of force, became the preferred unit of measurement of force. Although the pound-force may still be used in certain contexts, it is not a widely used unit of measurement.
kilogram-force
Definition: A kilogram-force (symbol: kgf) is a unit of force in the gravitational metric system. It is defined as the magnitude of force applied to one kilogram of mass under the condition of standard gravity (9.80665 m/s2). One kilogram-force is therefore equal to 9.80665 N.
History/origin: Although the kilogram-force was used in some imprecise measurements of force in the past, it was not until 1901 when the General Conference of Weights and Measures adopted a standard acceleration due to gravity of 9.80665 m/s2 that the kilogram-force became a well-defined measurement of force. Prior to the adoption of the International System of Units (SI) in 1960, the kilogram force was used around the world in the space programs of countries like China, Germany, and Russia.
Current use: The kilogram-force has largely been replaced by the Newton, the SI derived unit of force, but is still used in China, and in some cases, by the European Space Agency, an intergovernmental agency consisting of 22 member states.
