Mass Calculator

Enter the total density of an object, and the total volume that object occupies to calculate the total mass. Mass is defined as the amount of matter in an object. The higher the density the higher the mass.

Mass Formula

The following formula is used to calculate a mass.

m = F/a

  • Where F is the force
  • a is the acceleration.

It can also be described as the following:

m = p X V

  • Where p is the density
  • V is the volume

Mass Definition

Mass is a measure of how much matter occupies a certain space. The higher the mass, the higher the density if the volume stays the same. Mass is no to be confused with weight. Weight is a measure of force on an object due to gravity, which is a function of the mass of the object and the mass of the opposing object.

For example, on a different planet the mass of an object is going to stay the same, but the weight of that object will change. That’s because the mass of the planet effects the weight, and that mass has changed.

How to calculate mass

Lets look at an example of how you could calculate mass using the equations above. The first step is to determine the density of an object. This can be done several ways, but on of the more popular ways is through the use of buoyancy. This uses the known properties of water to calculate density.

Lets assume we find our object is 25g/m^3.

Next we need to find how much volume our object takes up. This can be done simply through measuring the length, width, and height and multiplying those numbers. Let’s assume we find its 10 cubic meters.

Now using the equation above, multiply the density times volume and we get 250 grams.
