Supported Units

  • Newton-meter (N·m) — The SI unit of torque. Used worldwide in automotive specifications, engineering, and physics. A force of one newton applied at a perpendicular distance of one meter from the axis of rotation.
  • Kilonewton-meter (kN·m) — 1,000 N·m. Used for large-scale industrial torque such as wind turbine shafts, large bolted connections, and heavy machinery.
  • Foot-pound force (ft·lbf) — The primary imperial torque unit used in the US for automotive specs, bolt torque, and mechanical engineering. 1 ft·lbf = 1.3558 N·m.
  • Inch-pound force (in·lbf) — 1/12 of a foot-pound. Used for smaller fasteners, precision instruments, and electronic equipment. 1 in·lbf = 0.1130 N·m.
  • Kilogram-force meter (kgf·m) — A gravitational metric unit. 1 kgf·m = 9.807 N·m. Still used in some Asian automotive markets and older European specifications.
  • Kilogram-force centimeter (kgf·cm) — 1/100 of kgf·m. Used for small motors, servo specifications, and precision applications.
  • Dyne-centimeter (dyn·cm) — The CGS unit of torque. 1 dyn·cm = 10⁻⁷ N·m. Used in some scientific contexts.
  • Inch-ounce force (in·ozf) — Used for very small torque values like watch mechanisms, electronic connectors, and micro-fasteners.

Key Conversion Factors

  • 1 N·m = 0.7376 ft·lbf = 8.851 in·lbf = 0.10197 kgf·m
  • 1 ft·lbf = 1.3558 N·m = 12 in·lbf = 0.1383 kgf·m
  • 1 kgf·m = 9.807 N·m = 7.233 ft·lbf

Frequently Asked Questions

What torque units are supported?

Eight units: Newton-meter (N·m), Kilonewton-meter (kN·m), Foot-pound force (ft·lbf), Inch-pound force (in·lbf), Kilogram-force meter (kgf·m), Kilogram-force centimeter (kgf·cm), Dyne-centimeter (dyn·cm), and Inch-ounce force (in·ozf).

What is the difference between N·m and ft·lbf?

N·m (Newton-meter) is the SI torque unit used worldwide. ft·lbf (foot-pound) is the imperial unit used in the US. 1 N·m = 0.7376 ft·lbf, or equivalently, 1 ft·lbf = 1.3558 N·m.

How do I convert engine torque specs?

European and Asian car specs use N·m. American specs use ft·lbf. For example, 400 N·m = 295 ft·lbf. For bolt torque specs, use the same conversion: 100 ft·lbf = 135.6 N·m.

What is kgf·m?

Kilogram-force meter is a gravitational metric unit still used in some Asian and European contexts. 1 kgf·m = 9.80665 N·m. It represents the torque produced by a 1 kg mass at 1 meter from the pivot.
