Torque Calculator

Torque is the rotational equivalent of force, a measure of how effectively a force twists an object around a pivot. It equals the applied force multiplied by the length of the lever arm and by the sine of the angle between the force and the arm, so a force applied at a right angle produces the most torque for a given distance. This calculator takes a force in newtons, a lever arm in meters and an angle in degrees and returns the torque in newton meters. Torque governs how tight a bolt is, how much a wrench turns, and how motors and engines deliver rotational power. If you push straight down on a horizontal wrench the angle is ninety degrees and the sine is one. Enter your values and the torque updates live in your browser.
