How to Convert Foot-Pounds to Newton-Meters

To convert a measurement in foot-pounds to a measurement in newton-meters, multiply the torque by the following conversion ratio: 1.355818 newton-meters/foot-pound.

Since one foot-pound is equal to 1.355818 newton-meters, you can use this simple formula to convert:

newton-meters = foot-pounds × 1.355818

The torque in newton-meters is equal to the torque in foot-pounds multiplied by 1.355818.

For example, here's how to convert 5 foot-pounds to newton-meters using the formula above.
newton-meters = (5 lb-ft × 1.355818) = 6.77909 Nm

How Many Newton-Meters Are in a Foot-Pound?

There are 1.355818 newton-meters in a foot-pound, which is why we use this value in the formula above.

1 lb-ft = 1.355818 Nm

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

What Are Foot-Pounds?

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.

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.

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.
