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.
How to use Torque Calculator
- Enter the applied force in newtons.
- Enter the lever arm length and the angle in degrees.
- Read the resulting torque in newton meters.
Frequently asked questions
What is the torque formula used here?
Torque equals force times lever arm length times the sine of the angle, written tau equals F r sin(theta).
Why does the angle matter?
Only the component of force perpendicular to the lever arm creates torque, so a force at 90 degrees gives the maximum turning effect.
What units does it use?
Force is in newtons and length in meters, giving torque in newton meters.
