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 sthène (symbol sn), sometimes spelled (or misspelled) sthéne or sthene (from the Greek σθένος (sthenos) meaning "force"), is an obsolete unit of force or thrust in the metre–tonne–second system of units (mts) introduced in France in 1919.
