Frequently Asked Questions
What is torque?
Torque (also called moment of force) is the product of a force F and the perpendicular distance r from the axis of rotation: M = F × r. The SI unit is the newton-metre (N·m). Although N·m is dimensionally equivalent to joule (energy), torque is a vector quantity physically distinct from energy. Torque appears in bolt tightening, engine output, and bicycle components.
What is the difference between kgf·m and kp·m?
kgf·m (kilogram-force metre) and kp·m (kilopond-metre) denote the same unit — the torque produced by 1 kg weight over a 1 m moment arm: 1 kgf·m = 1 kp·m = 9.80665 N·m. German technical texts prefer kp·m; international usage favours kgf·m.
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, and service manuals.
What is the SI unit of torque?
The SI unit of torque is the newton-metre (N·m): the torque produced by 1 N of force over a 1 m moment arm. Kilonewton-metres (kN·m) are used in structural engineering; kilogram-force metres (kgf·m) and pound-feet (lb·ft) are common engineering units without SI status.
Are these torque conversions exact?
Yes. All factors are exact defined constants: 1 kgf·m = 9.80665 N·m (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.
