Nm to lb-ft Converter

Convert newton-metres to pound-feet and back — the torque conversion every car and bike workshop manual needs.

Convert N·m ⇄ lb-ft

73.756 lb-ft
100 N·m = 73.756 lb-ft

Formula: 100 N·m (N·m × 0.73756) = 73.756 lb-ft

How the nm to lb-ft conversion works

The conversion is: pound-feet = newton-metres × 0.73756. One newton-metre is the torque of one newton applied at one metre, and in imperial units that works out to 0.73756 lb-ft. Going the other way, N·m = lb-ft ÷ 0.73756 (equivalently, multiply lb-ft by 1.35582).

Watch the spelling: torque is pound-feet (lb-ft), a force times a distance. Pound-feet is not foot-pounds of energy, though the two are numerically equal in this conversion. European and Japanese workshop manuals quote N·m; American manuals quote lb-ft — this converter bridges the two, and kgm to Nm covers the older kilogram-metre figures still found on some specs.

Worked example: a wheel-nut torque of 120 N·m is 120 × 0.73756 = 88.51 lb-ft. And a classic 200 lb-ft American V8 figure is 200 ÷ 0.73756 = 271.16 N·m.

Handy benchmarks: 50 N·m = 36.88 lb-ft, 100 N·m = 73.76 lb-ft, 200 N·m = 147.51 lb-ft and 500 N·m = 368.78 lb-ft.

nm to lb-ft converter questions

How many lb-ft are in 1 Nm?
0.73756 lb-ft. Multiply newton-metres by 0.73756 to get pound-feet.
How do I convert Nm to lb-ft?
Multiply by 0.73756: lb-ft = N·m × 0.73756. So 120 N·m is 120 × 0.73756 = 88.51 lb-ft.
What is 100 Nm in lb-ft?
73.76 lb-ft. 100 × 0.73756 = 73.756, rounded to 73.76 lb-ft.
Is lb-ft the same as ft-lb?
For torque, yes — lb-ft and ft-lb are used interchangeably, and both mean a force of one pound acting at a distance of one foot. Torque wrenches may be marked either way; the number is the same.
How do I convert lb-ft back to Nm?
Divide by 0.73756, or multiply by 1.35582: N·m = lb-ft × 1.35582. Switch the direction above to do it.
