Nm to in-lbs Converter
1 Nm equals 8.8507 in-lbs, so a 5 Nm bolt spec is 44.25 in-lbs. This Nm to in-lbs converter switches between newton-meters and inch-pounds in either direction. Use it when a bike stem, electronics fastener, firearm accessory, or small engine manual gives torque in the other system.
Quick answer
1 inch-pound is 0.112984829 newton-meters.
Result
44.253729 in-lb
What this tells you
- •1 inch-pound is 0.112984829 newton-meters.
- •To convert Nm to in-lbs, multiply by 8.85074579.
- •To convert in-lbs to Nm, multiply by 0.112984829.
- •Inch-pounds are common for small fasteners where foot-pounds would be too coarse.
How to Use

How It Works
Formula
in-lbs = Nm × 8.85074579One inch-pound equals 0.1129848290276167 newton-meters. Divide Nm by 0.1129848290276167 to get inch-pounds, or multiply inch-pounds by 0.1129848290276167 to get newton-meters.

Worked Examples
Convert 5 Nm to in-lbs
Multiply 5 by 8.85074579 to get 44.25 in-lbs, a common range for bike cockpit bolts.
Convert 150 in-lbs to Nm
Multiply 150 by 0.112984829 to get 16.95 Nm, a useful size for small engine and automotive fasteners.

Common mistakes
- Mixing up inch-pounds and foot-pounds. One foot-pound is 12 inch-pounds, so using the wrong wrench scale can overshoot badly.
- Rounding 1 Nm to 9 in-lbs for precision work. That shortcut is close, but it can push a carbon part or small screw out of spec.
- Treating in-lb as a weight measurement. Here it means inch-pound force, a torque unit, not a package weight.
