What Are Foot-Pounds?

Foot-pounds are a measurement of torque.

The foot-pound, or pound-foot or pound-force foot, is a US customary unit of torque. Foot-pounds can be abbreviated as lb-ft, and are also sometimes abbreviated as lbf-ft or ft-lb. For example, 1 foot-pound can be written as 1 lb-ft, 1 lbf-ft, or 1 ft-lb.

How Much Is a Foot-Pound?

One foot-pound is equal to the torque that results from applying one pound-force perpendicularly to a one-foot-long moment arm.

One foot-pound is equal to 12 inch-pounds.

While the foot-pound is a commonly used term, it is technically not the correct verbiage to express torque. Pound-foot (or pound-feet) is the correct way to express this measurement of torque.

How to Convert Foot-Pounds

To convert foot-pounds to another unit of torque, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for foot-pounds in the conversion table below.

Then, multiply the torque measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

foot-pounds × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
