FAQ

How many in-lbs is 1 Nm?

1 N·m ≈ 8.851 in-lb. The exact relation goes the other way: 1 in-lb = 0.1129848290276167 N·m, so in-lb = N·m ÷ 0.1129848290276167.

Where does the factor 0.1129848290276167 come from?

An inch-pound of torque is one pound-force acting on a one-inch lever: 1 in-lb = 1 lbf × 1 in. The pound-force is exactly 4.4482216152605 N and the inch is exactly 0.0254 m, so their product, 0.1129848290276167 N·m, is exact too. It is one twelfth of a foot-pound.

When are inch-pounds used instead of foot-pounds?

For small torques: bicycle stems and seat posts, electronics, carburetor and valve-cover bolts. 1 ft-lb = 12 in-lb exactly, so an in-lb scale reads twelve times higher than a ft-lb scale for the same torque.

How do kgf·m relate to in-lbs?

1 kgf·m = 9.80665 N·m exactly, which is about 86.8 in-lb. Older torque tables print kgf·m, so every answer here also shows it.
