Torque Calculator

If you want to determine an object's rotating energy results, you can use this torque calculator.

In physics, torque is a force's momentum that tends to rotate the body or an object. The SI unit of torque is newton meter Nm (Newton Meter).

For better understanding, suppose a thing (like a wheel) rotating around a point r also called a pivot point. At a distance d, if you put a force to the pivot point, although the power will be put at the straight line (90 degrees), the object starts its rotation.


Formula of Torque Calculator

If you want to find the torque in an object, you can use the formula listed below, or to determine it instantly, you can use our calculator.

τ = r F sin(θ)

There are three various factors on which torque depends.

  • = Lever arm - It’s the distance between the pivot point and the application's force point

  • F = Force on an object/thing. (where force calculator can help you calculate force by Mass and Acceleration)

  • θ = Angle among vector force and the lever arm. usually it equivalent to 90° and additionally

  • τ = torque

For more clear understanding, let us have an example below:

Suppose a force 120N is acting on a door's lock at 90°, whereas the lever arm is 0.5m long. Find the torque that applies to a lock.

Given data

F = 120N
r = 0.5m
θ = 90°

To Find

Torque = ?


To find the torque, we can use the formula listed below:

τ = r F sin(θ)

Putting values in formula above:

τ = 0.5 x 120 x sin(90°)
τ = 60N·m
