The foot-pound and the inch-pound are two of many different units used to measure work and torque. These two customary units are equal to the force of 1 lb. acting through the distance of one foot and 1 lb. acting through the distance of one inch. Because both units are based on the pound and a customary unit of length, converting one to the other is a straightforward process.
