## What Are Inch-Pounds?

Inch-pounds are a measurement of torque.

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

## How Much Is an Inch-Pound?

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

One inch-pound is equal to 1/12 of a foot-pound. Thus, 12 inch-pounds of torque is equal to one foot-pound.

While inch-pounds are commonly used to describe torque, the correct verbiage is pound-inches.

## How to Convert Inch-Pounds

To convert inch-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 inch-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.

inch-pounds × conversion factor = result

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