Torque units — newton-metres, kilogram-force metres, pound-feet and more

The newton-metre (N·m) is the SI unit of torque. Torque is the product of a force and the perpendicular moment arm to the axis of rotation — it describes rotational tendency, not the force itself. The kilogram-force metre (kgf·m) — called Kilopondmeter (kp·m) in German — equals the torque produced by 1 kg weight over 1 m arm: 1 kgf·m = 9.80665 N·m. The pound-foot (lb·ft) is used in US automotive specifications: 1 lb·ft = 1.3558 N·m. The pound-inch (lb·in = 1/12 lb·ft) and ounce-inch (oz·in = 1/16 lb·in) appear on smaller fasteners, bicycle components, and electric motor specs.

All conversion factors are exact defined constants — there is no measurement uncertainty. For more torque unit pairs, visit the torque conversion hub.

Frequently asked questions

How much is 1 lb·ft in kN·m?

1 lb·ft equals 0.001356 kN·m.

How much is 10 lb·ft in kN·m?

10 lb·ft equal 0.01356 kN·m.

How do I convert lb·ft to kN·m?

Divide the value in lb·ft by 737.5621 to get kN·m.

What is torque?

Torque (also called moment of force) is the product of a force and the perpendicular distance from the axis of rotation (moment arm): M = F × r. The SI unit is the newton-metre (N·m). Although N·m is dimensionally equivalent to energy (joule), torque is a vector quantity physically distinct from energy. Typical applications: bolt tightening, engine output, bicycle mechanics.

How many N·m is 1 lb·ft?

1 lb·ft (pound-foot) equals exactly 1.3558179483 N·m. Conversely, 1 N·m ≈ 0.7376 lb·ft. The pound-foot is the standard torque unit in US automotive specifications (lug nuts, head bolts, service manuals).

Are these torque conversions exact?

Yes. All factors are exact defined constants: 1 kgf·m = 9.80665 N·m (standard gravity, exact), 1 lb·ft = 1.3558179483314004 N·m (exact), 1 lb·in = 0.1129848290276167 N·m (exact), 1 oz·in = 0.0070615518142 N·m (exact). There is no measurement uncertainty — only floating-point rounding at the last digit.
