Joule to Pound-Force Inch
Pound-force inch (lbf·in) is a unit of torque and energy commonly used in precision mechanical engineering, particularly in applications requiring fine control and measurement. One pound-force inch represents the torque produced by one pound of force applied at a distance of one inch from the axis of rotation.
1 lbf·in = 0.112985 J
The exact conversion factor between pound-force inches and joules, based on the international pound and inch definitions.
