How to convert newton m to lb in

Multiply N·m by 8.8507457913. The factor combines 1 N = 0.2248089431 lbf with 1 m = 39.3700787 in: 0.2248089 × 39.37008 = 8.8507458.

Example: a 6 N·m spec on a laptop hinge screw equals 6 × 8.85075 = 53.10 lb·in.

lb·in vs lb·ft — pick the right scale

One pound-foot is twelve pound-inches, so lb·in suits torques under about 15 N·m where lb·ft values would be awkward fractions. Bicycle components, electronics, and small engine fasteners are typically specified in lb·in.

For larger automotive torques, use our newton meters to ft lbs converter instead.

Questions, answered

Frequently asked

How many lb·in in 10 N·m? +
10 × 8.8507458 = 88.51 lb·in (equivalently 7.376 lb·ft).
Are lb·in and in·lb different? +
No — both denote pound-force acting on a one-inch lever. The order is just convention.
How do I convert lb·in back to N·m? +
Multiply by 0.1129848. So 50 lb·in = 5.65 N·m.
