Convert pound force foot to j
Pound-Force Foot
The pound-force foot (lbf·ft) is a unit of energy or torque in the imperial and US customary systems equal to the work done by a force of one pound-force acting through a distance of one foot, equivalent to approximately 1.35582 joules. It is commonly used in North American engineering to express engine torque, structural loads, and fastener specifications. The pound-force foot and foot-pound force are numerically identical but distinguished by context.
Joule
The joule (/dʒaʊ,dʒuːljawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
