FAQ

How many ft-lbs is 1 Nm?

1 N·m ≈ 0.7376 ft-lb. The exact relation goes the other way: 1 ft-lb = 1.3558179483314004 N·m, so ft-lb = N·m ÷ 1.3558179483314004.

Where does the factor 1.3558179483314004 come from?

A foot-pound of torque is one pound-force acting on a one-foot lever: 1 ft-lb = 1 lbf × 1 ft. The pound-force is exactly 4.4482216152605 N and the foot is exactly 0.3048 m, so their product, 1.3558179483314004 N·m, is exact too.

Is a foot-pound of torque the same as a foot-pound of energy?

The number is the same, the meaning is not. Torque is force times lever arm (strictly a pound-foot, written ft-lb on most wrenches); work and energy are force times distance (a foot-pound, in joules in SI). This page converts torque.

How do kgf·m relate to ft-lbs?

1 kgf·m = 9.80665 N·m exactly, which is about 7.233 ft-lb. Older torque tables print kgf·m, so every answer here also shows it.
