Convert pound force inch to j
Pound-Force Inch
The pound-force inch (lbf·in) is a unit of torque or energy in the imperial system equal to one twelfth of a pound-force foot, approximately 0.112985 joules. It is widely used in mechanical engineering and manufacturing to specify the torque of small motors, screws, and precision instruments. Specifications for electric motors and hand tools commonly express torque limits in pound-force inches.
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).
