Newton-Meters to Inch-Pounds Conversion (Nm to lb-in)

How to Convert Newton-Meters to Inch-Pounds

To convert a measurement in newton-meters to a measurement in inch-pounds, multiply the torque by the following conversion ratio: 8.850746 inch-pounds/newton-meter.

Since one newton-meter is equal to 8.850746 inch-pounds, you can use this simple formula to convert:

inch-pounds = newton-meters × 8.850746

The torque in inch-pounds is equal to the torque in newton-meters multiplied by 8.850746.

For example, here's how to convert 5 newton-meters to inch-pounds using the formula above.

inch-pounds = (5 Nm × 8.850746) = 44.253729 lb-in

How Many Inch-Pounds Are in a Newton-Meter?

There are 8.850746 inch-pounds in a newton-meter, which is why we use this value in the formula above.

1 Nm = 8.850746 lb-in

Newton-meters and inch-pounds are both units used to measure torque. Keep reading to learn more about each unit of measure.

What Are Newton-Meters?

One newton-meter is equal to the torque that results from applying a force of one newton perpendicularly to a one-meter-long moment arm.

Newton-Meters vs. Joules

While the expression of the newton-meter (N·m) is algebraically similar to the joule, the newton-meter is a measure of the force required to rotate an object about its axis. The joule, on the other hand, is the energy equal to the force required to move an object a distance of one meter.

In practical terms, if you were to apply a force of one newton at the end of a one-meter-long wrench, you would be exerting a torque of one newton-meter. If you apply a force of one newton to push an object over a distance of one meter, you would be exerting the energy of one joule.

The newton-meter, or newton-metre, is an SI unit of torque in the metric system. Newton-meters can be abbreviated as Nm; for example, 1 newton-meter can be written as 1 Nm.

What Are Inch-Pounds?

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.

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.
