If the mass m is measured in kilograms and the acceleration a is measured in meters per second squared, then the unit of force is kilogram x meter/second squared. This unit is called the newton: 1 N = 1 kg x 1 m/sÂ².
The pound-force (symbol: lbf, or lbf) is a unit of force used in some systems of measurement including English Engineering units and the British Gravitational System. Pound force should not to be confused with foot-pounds or pound-feet, which are units of torque, and may be written as lbÂ·ft or lbfÂ·ft.
