The foot-pound force (symbol: ft·lbf or ft·lb), sometimes erroneously referred to as feet per pound (symbol: ft/lb), is a unit of work or energy in the Engineering and Gravitational Systems in United States customary and imperial units of measure. It is the energy transferred upon applying a force of one pound-force (lbf) through a linear displacement of one foot. The corresponding SI unit is the joule.
