Convert pound-force to ton-force (long)
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.
ton-force (long)
Definition: Ton-force (long) is a measure of force. For conversion purposes, its value is 9964.0164181707 times the reference unit, newton.
