Foot-pounds (ft⋅lb)

Definition

A foot-pound (ft⋅lb) is an imperial unit of energy equal to the work done when a force of one pound-force moves an object one foot. It equals approximately 1.35582 joules.

History

The foot-pound has been used in English-speaking countries since the early days of mechanical engineering. It was the standard unit for torque and mechanical work before the joule gained prominence.

Current use

Foot-pounds are widely used in the US for measuring torque in automotive and mechanical applications, firearm muzzle energy, and mechanical work in engineering specifications.

Inch-pounds (in⋅lb)

Definition

An inch-pound (in⋅lb) is an imperial unit of energy and torque equal to one-twelfth of a foot-pound, or approximately 0.112985 joules.

History

The inch-pound evolved as a finer subdivision of the foot-pound for applications requiring greater precision in mechanical and manufacturing contexts in Anglo-Saxon engineering traditions.

Current use

Inch-pounds are used in precision engineering, aerospace fastener specifications, small engine torque settings, and electronic assembly where fine torque control is essential.
