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

**First, determine the mass of the object**Through calculations determine the actual mass of the object.

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

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