Convert foot pound to j
Foot-Pound
The foot-pound (symbol: ft·lbf) is a unit of energy 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, approximately 1.35582 joules. It is commonly used to express torque, impact energy in firearms (muzzle energy), and mechanical work in engineering. One foot-pound equals 12 inch-pounds.
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).
