Oct 18, 2018· Torque (also called moment — mostly by engineers) is calculated by multiplying force and distance. The SI units of torque are newton-meters, or N*m (even though these units are the same as Joules, torque isn't work or energy, so should just be newton-meters). In calculations, torque is represented by the Greek letter tau: τ.
