In physics, torque is a vector quantity that can be thought of as a rotational or angular force that causes a change in rotational motion. This force is defined as the linear force multiplied by the radial length. In the International System of Units, torque is measured in newton-meters. In the Imperial System of Units, it is measured in foot-pounds. The Greek letter for torque is tau.

Torque calculation

Torque: M = F*I

M = torque

F = Force
