Best Answer: Torque is a twisting force. It is the power output of an engine at one specific point in time. The first number, 200 in your expample, is the amount of torque. In America is is measured in foot/pounds. The second number, 400 in your example, is the RPM where that torque number occurs.
Torque Calculation. Torque is defined as: The measure of the force applied to produce rotational motion (usually measured in foot-pounds). Torque is determined by multiplying the applied force by the distance from the pivot point to the point where the force is applied.1  In the English system, torque is measured in foot-pounds or inch-pounds. 2  In the Metric system, torque is measured in Newton-meters. 3  8.851 inch-pounds = 1 Newton-meter.orque is determined by multiplying the applied force by the distance from the pivot point to the point where the force is applied. 1  In the English system, torque is measured in foot-pounds or inch-pounds.
