FAQ

How many Nm is 1 in-lb?

Exactly 0.1129848290276167 N·m; for mental math, 1 in-lb ≈ 0.113 N·m. Formula: N·m = in-lb × 0.1129848290276167.

Why is the factor exactly 0.1129848290276167?

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, has no rounding in it.

How do I turn inch-pounds into foot-pounds?

Divide by 12: a foot is 12 inches, so 1 ft-lb = 12 in-lb exactly. Wrench specs under about 20 ft-lb are usually given in in-lb.

How many kgf·m is an in-lb?

About 0.01152 kgf·m, since 1 kgf·m = 9.80665 N·m exactly. Older torque tables print kgf·m, so every answer here also shows it.
