How many foot-pounds is a newton metre?

1 N·m is about 0.7376 lbf·ft, and 1 lbf·ft is about 1.3558 N·m.

Result

0.7376 lbf·ft

1 newton metre is about 0.7376 pound-force feet

  • The other way round: 1 lbf·ft ≈ 1.356 N·m.

How it works

Torque is a force times the distance from the axis it turns around. The SI unit is the newton metre (N·m): one newton pushing at the end of a one-metre lever. Every unit here is converted through newton metres.

A foot-pound (lbf·ft) is one pound-force at one foot: 0.45359237 kg × 9.80665 m/s² × 0.3048 m ≈ 1.3558 N·m. So 100 N·m ÷ 1.3558 ≈ 73.76 lbf·ft. An inch-pound is a twelfth of a foot-pound, and a kilogram-force metre is exactly 9.80665 N·m.

The definitions come from NIST Special Publication 811. Torque values in manuals are often rounded, so a converted setting is only as precise as the number you start from.

Frequently asked questions

How do I convert N·m to ft·lb?

Multiply by about 0.7376. For example, 120 N·m × 0.7376 ≈ 88.5 lbf·ft.

What is 50 N·m in foot-pounds?

About 36.9 lbf·ft.
