About torque units
Torque, also called moment of force, is the turning effect of a force about an axis: force times the distance from the axis. Its SI unit is the newton meter (N·m).
One pound-force foot is exactly 1.3558179483314004 N·m and equals 12 pound-force inches. One kilogram-force meter is exactly 9.80665 N·m. Torque and energy share the same dimensions, but torque is written in N·m, never in joules.
Frequently asked questions
- How do I convert lb-ft to N·m?
- Multiply by about 1.35582. For example, 100 lbf·ft is about 135.58 N·m. One N·m is about 0.73756 lbf·ft.
- Are foot-pounds and pound-feet the same?
- For torque, yes: both mean one pound-force acting at one foot. Engineers often write lbf·ft for torque and ft·lbf for energy to keep the two apart.
- Is moment of force the same as torque?
- Yes. Both are force times lever arm and both use N·m, so this page covers both.
- How many kilogram-force meters are in one newton meter?
- One newton meter ≈ 0.1019716213 kgf·m (kilogram-force meters).
- How many kilogram-force centimeters are in one newton meter?
- One newton meter ≈ 10.19716213 kgf·cm (kilogram-force centimeters).
- How many pound-force feet are in one newton meter?
- One newton meter ≈ 0.7375621493 lbf·ft (pound-force feet).
