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.

• In the English system, torque is measured in “foot-pounds” or “inch-pounds”.
• In the Metric system, torque is measured in “Newton-meters”.
• 8.851 inch-pounds = 1 Newton-meter
• 1 foot-pound = 12 inch-pounds
• 16 ounce-inches = 1 inch-pound
• 1 Newton = 1 kilogram-meter per second squared
• Torque = Force x Moment Arm
