Torque is a twisting force, and the SI way of measuring torque is Newtons for the force and metres for the distance this force is exerted at.

You will come across many different ways of measuring torque, some examples being lb/ft or lbf/ft (Imperial) or kgf/mm (metric). They all have common elements of a force applied across a distance.
