Enter the total force and the distance from the rotation point into the calculator to determine the moment of force.

Moment of Force Formula

The following equation is used to calculate the Moment of Force.

MoF = F * L

  • Where MoF is the moment of force (N*m)
  • F is the total force (N)
  • L is the total length (m)

To calculate a moment of force, multiply the total force by the total length from the axis of rotation the force is applied at.

What is a Moment of Force?


A moment of force is defined as the total moment exerted on an object by a force at a given distance.

How to Calculate Moment of Force?

Example Problem:

The following example outlines the steps and information needed to calculate Moment of Force.

First, determine the total force . In this example, the total force is found to be 50 N.

Next, determine the total length. For this problem, the total length is found to be 3m.

Finally, calculate the moment of force using the formula above:

MoF = F * L

MoF = 50 * 3

MoF = 150 N-m
