Mass to Weight Calculator

Enter any mass value and the acceleration due to gravity. The calculator will convert your mass to weight in your units of choice.

Mass to Weight Formula

The following equation is used to convert a mass unit to weight unit.

W = M*A

  • Where W is the weight
  • M is the mass
  • A is the acceleration

If you have some understanding of physics, you might notice that this looks similar to an equation you’ve seen. That equation is F=ma or force equals mass times acceleration. The reason that looks familiar is because they actually are one in the same. Weight is actually a measure of force, it’s just describe as a weight to differentiate it from other forces.

how to convert mass to weight

  1. First, determine the mass of the object

    Through calculations determine the actual mass of the object.

  2. Next, determine the acceleration

    Calculate or measure the acceleration on the object due to gravity. On earth this is 9.81 m/s^2.

  3. Calculate the weight

    Calculate the weight, also known as force, acting on the object due to gravity.
