Force and torque


Unit of force: newton (N)

The SI unit of force is the newton (symbol N), which is the force required to accelerate a one kilogram mass at a rate of one meter per second squared, or kg·m·s−2​. Force is a derived unit in the SI with a special name and symbol.

Unit of torque: newton metre (N m)

The quantity torque (or moment of force) may be thought of as the cross product of force and distance and the SI unit for torque is Newton metre, N m (m2 kg s-2). Even though N m is the same as Joule, torque is not work or energy and hence torque should only be expressed in newton metres and not in Joules (J).
