How it's calculated

Formula

τ=F×d\tau = F \times d
F
— Applied force (perpendicular to the lever arm)
d
— Distance from the pivot point

What is the Torque Calculator?

Torque is the rotational equivalent of force — how much a force applied at a distance from a pivot tends to rotate an object.

How to use it

  1. 1 Enter the applied force.
  2. 2 Enter the distance from the pivot point (assuming the force is perpendicular to the lever arm).

Worked examples

50N at 0.3m

Torque is 15 N·m.

Frequently asked questions

What if the force isn't perpendicular to the lever arm?

This calculator assumes a perpendicular force — for an angled force, multiply by sin(angle) to get the effective perpendicular component first.
