Newton meter
- Definition
- A newton meter (symbol: N·m) is the SI unit of torque, or moment of force. One newton meter is the turning effect of a force of one newton applied at the end of a one-meter lever arm, perpendicular to it.
- History / origin
- It is a derived SI unit combining the newton - the unit of force named after Sir Isaac Newton - with the meter. A newton meter is dimensionally the same as the joule, but the joule is reserved for energy while torque is expressed in newton meters.
- Current use
- The newton meter is the standard torque unit worldwide for engineering, physics and modern vehicle specifications, where fastener, axle and engine torques are quoted in N·m.
Pound-force foot
- Definition
- A pound-force foot (symbol: lbf·ft), usually written lb-ft or ft-lb, is a unit of torque in the imperial and US customary systems. It is the torque from one pound-force acting on a one-foot lever arm, and equals 1.355818 newton meters.
- History / origin
- It is built from the pound-force - the weight of a one-pound mass at standard gravity - and the foot. For torque it is written pound-feet (lbf·ft), while the identical product used for energy is written foot-pounds; the word order signals which quantity is meant.
- Current use
- Pound-feet are the everyday torque unit in the United States, especially in automotive work, where wheel-nut, spark-plug and cylinder-head torques are routinely specified in lb-ft alongside or instead of newton meters.

How to convert newton meters to pound-force feet
To convert newton meters to pound-feet, multiply the newton-meter value by 0.7375621212. For example, 100 N·m = 100 × 0.7375621212 = 73.76 lbf·ft (or divide by 1.355818).
One pound-foot is defined here as 1.355818 newton meters, so to go from newton meters to pound-feet you divide by 1.355818 - equivalently, multiply by 0.7375621212:
lbf·ft = N·m ÷ 1.355818 = N·m × 0.7375621212
1 N·m = 0.7375621212 lbf·ft · 1 lbf·ft = 1.355818 N·m
Example. To convert 40 N·m to pound-feet, multiply by 0.7375621212: 40 N·m = 40 × 0.7375621212 = 29.5 lbf·ft. Going the other way, 50 lbf·ft is 50 × 1.355818 = 67.79 N·m.
When you need to convert newton meters to pound-force feet
Newton-meter to pound-foot conversion comes up whenever a metric torque spec meets an imperial torque wrench. Common cases:
- Following US repair manuals that list torque in pound-feet when your wrench reads newton meters.
- Tightening wheel nuts, lug bolts and suspension fasteners to a lb-ft figure on a car specified in N·m.
- Comparing engine and chassis torque specs between European (N·m) and US (lb-ft) service data.
- Setting a click-type torque wrench scaled in pound-feet from a metric specification.
- Checking that a metric bolt-torque table agrees with an imperial one before assembly.
Frequently asked questions
How do I convert newton meters to pound-feet?
Multiply the newton-meter value by 0.7375621212. For example, 100 N·m equals about 73.76 lbf·ft. The same factor works for any value.
How many pound-feet is 1 newton meter?
One newton meter equals 0.7375621212 pound-feet, a little under three-quarters of a pound-foot.
How many pound-feet is 100 N·m?
100 N·m equals about 73.76 pound-feet (73.756212117 lbf·ft to be exact).
Is pound-feet the same as foot-pounds?
For torque the magnitude is the same. Torque is usually written pound-feet (lbf·ft) and energy is written foot-pounds, but the conversion number is identical.
What is the formula to convert N·m to lb-ft?
Divide the newton-meter value by 1.355818, or multiply by 0.7375621212, because one pound-foot equals 1.355818 newton meters.
How do I convert pound-feet back to newton meters?
Multiply the pound-foot value by 1.355818. For example, 50 lbf·ft equals 67.79 N·m. For the reverse direction use our pound-feet to newton meters converter.
