torque A turning or twisting force. Torque causes torsion, which is the twisting of a normally rigid body. In the British Commonwealth and the US, torque is commonly measured in foot pounds or inch pounds. Elsewhere, the metric system is used and torque is measured in kilogram meters or centimeter grams.
Whether measured in the English or metric system, the formula for torque is the same:
Torque = Length x Force
