Not to be confused with Pound-foot (torque) or Foot-poundal.
The foot-pound force (symbol: ft⋅lbf, [1] ft⋅lbf,[2] or ft⋅lb [3]) 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, though in terms of energy, one joule is not equal to one foot-pound.
