Newton Meter

N·m

Definition

The newton meter (N·m) is the SI unit of moment of force, representing the torque produced by a force of one newton applied at a distance of one meter from the axis of rotation. It is the standard unit for measuring rotational force in physics and engineering.

History/Origin

Derived from the SI base units of force (newton) and length (meter), the newton meter became the standard unit for moment of force in the International System of Units. It is fundamental in mechanics and rotational dynamics.

Current Use

Widely used in mechanical engineering, physics, and automotive applications to measure torque, rotational force, and moment of force in engines, motors, and mechanical systems.
