Enter the total mass of an object into the calculator to determine the force acting on the object due to gravity.

Weight to Force Formula

The following equation is used to calculate the Weight to Force.

F = m*a

  • Where F is the force (N)
  • m is the mass of the object (kg)
  • a is the acceleration due to gravity (9.81 m/s^2)

In this formula, the acceleration due to gravity is set as 9.81 m/s^2 for earth, but you can adjust this value in the calculator for other value.

What is Weight to Force?


Weight to force typically refers to mass to force. Since weight is technically already a “force” on a given mass, they are equal and can’t be converted between one another.

How to Calculate Weight to Force?

Example Problem:

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

First, determine the mass of the object. In this example, the mass of the object is found to be 50kg.

Next, determine the acceleration due to gravity. We will use Earth’s acceleration due to gravity of 9.81 m/s^2.

Finally, calculate the force from the weight using the formula above:

F = m*a

F = 50*9.81

F = 490.5 N
