Understanding the Units

What is a Foot-Pound?

A foot-pound (force) equals approximately 1.355818 newton-meters — the torque from one pound-force at one foot.

Common contexts: automotive (US), fastener torque (US).

What is a Newton Meter?

The newton-meter is the SI derived unit of torque, equal to the moment produced by one newton acting at a perpendicular distance of one meter.

Common contexts: mechanical engineering, fastener specs.

FAQ

How many newton meters are in one foot-pound?

One foot-pound equals approximately 1.35582 newton meters.

How do I convert foot-pounds to newton meters?

Multiply the number of foot-pounds by 1.35582. For example, 80 ft·lb × 1.35582 = 108.4656 N·m.

What is foot-pound torque?

A foot-pound (ft·lb) is an imperial unit of torque representing the rotational force from one pound-force applied at a distance of one foot from the pivot point.

Are foot-pounds and pound-feet the same?

For torque, foot-pounds (ft·lb) and pound-feet (lb·ft) refer to the same unit. "Pound-feet" is technically more correct per SI naming conventions, but both are widely used interchangeably.

How many newton meters are in 1 foot-pound?

1 ft·lb equals 1.35582 N·m.

How do you convert foot-pounds to newton meters?

Multiply the foot-pound value by 1.35582. Formula: N·m = ft·lb × 1.35582.

How many newton meters are in 5 foot-pounds?

5 ft·lb = 6.7791 N·m.

How do you convert newton meters back to foot-pounds?

Use the inverse formula: ft·lb = N·m ÷ 1.35582. For example, 1 N·m = 0.737561 ft·lb.

What is the difference between Foot-Pound and Newton Meter?

A foot-pound (force) equals approximately 1.355818 newton-meters — the torque from one pound-force at one foot. The newton-meter is the SI derived unit of torque, equal to the moment produced by one newton acting at a perpendicular distance of one meter.
