How to convert newton meters to pound-feet
- Take the value in newton meters.
- Use the formula pound-feet = newton meters × 0.7375621493.
- For example, 5 N·m is 3.69 lb·ft.
About newton meters and pound-feet
One newton meter is 0.737562 pound-feet. Multiply Nm by 0.7376 to get lb-ft, or multiply by 3/4 for a quick estimate that is about 1.7% high.
Torque specs for bolts, wheel nuts and engines are given in Nm in most of the world, while many US torque wrenches and service manuals use foot-pounds. Mechanics often say “foot-pounds” and engineers write “pound-feet” (lb·ft) for torque, but the numbers are the same.
Examples
- 5 N·m (a typical bike stem bolt) is 3.69 lb·ft
- 110 N·m (a common car wheel nut torque) is 81.13 lb·ft
- 400 N·m (a strong turbodiesel engine) is 295.02 lb·ft
- 1 N·m (one newton meter) is 0.738 lb·ft
