The pound-force (symbol: lbf, sometimes 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 be confused with foot-pounds or pound-feet, which are units of torque, and may be written as "lbf⋅ft". They should not be confused with pound-mass (symbol: lb), often simply called pounds, which is a unit of mass.

The dyne (symbol dyn, from Greek δύναμις, dynamis, meaning power, force) is a unit of force specified in the centimetre–gram–second system of units (CGS), a predecessor of the modern SI. One dyne is equal to 10 micronewtons, 10−5 N or to 10 nsn (nanosthenes) in the old metre–tonne–second system of units.
1 dyn = 1 g⋅cm/s2 = 10−5 kg⋅m/s2 = 10−5 N
1 N = 1 kg⋅m/s2 = 105 g⋅cm/s2 = 105 dyn
