What is a Torque Converter?

A torque converter translates rotational force measurements between unit systems. Newton-meters (N·m) is the SI unit of torque. Foot-pounds (ft·lb) and inch-pounds (in·lb) are used in the US for fastener specs and engine ratings. Kilogram-force meters (kgf·m) appear in older and some Asian engineering documents. Kilonewton-meters (kN·m) are used in structural engineering.

How to Use Torque Converter

  1. Type a torque value into any field (N·m, kN·m, ft·lb, in·lb, kgf·m, or N·cm).
  2. All other fields update instantly.
  3. Use quick example buttons for common reference torque values.
  4. Click Clear to reset all fields.

Frequently Asked Questions
How many ft·lb is 1 N·m?

1 N·m = 0.7376 ft·lb (foot-pounds).

How many in·lb is 1 N·m?

1 N·m = 8.851 in·lb (inch-pounds).

What is the difference between torque and force?

Force is a push or pull (measured in newtons). Torque is a rotational force —force applied at a distance from a pivot point. Torque = Force x Lever Arm length.

What is kgf·m used for?

Kilogram-force meter (kgf·m) is a legacy unit used in older engineering literature and some Asian countries. 1 kgf·m = 9.80665 N·m.
