About this tool: Torque Calculator

Calculate torque from force, lever arm and the angle between them.

The lever arm is the distance from the pivot to the point where force is applied. The angle is measured between that arm and the force: 90 degrees gives maximum torque and zero or 180 degrees gives zero torque. This tool returns the magnitude in newton-metres.

How the calculation works

M = F r sin(θ)
