The newton-meter is the SI derived unit of torque, equal to the rotational effect of a 1-newton force applied at a 1-meter lever arm.
Derived directly from the SI units of force and length, the newton-meter became the standard unit for expressing rotational effect in engineering.
Measurement system: International System of Units (SI, derived unit). SI equivalent: 1 N·m = 1 N × 1 m.
