Density to Weight Calculator

This density to weight calculator gives you a quick way to go from the density of an object made from a known substance to its weight, as long as you know its volume.

In this brief article, we will show you:

• The density to weight equation;
• How to calculator weight from density; and
• The difference between density and weight?

So how do we calculate weight using density and volume? By rearranging the equation for density, which is defined as the mass per unit volume:

where:

• $\rho$ – Density of the substance;
• $m$ – Weight (or mass); and
• $V$ – Volume.

So if we know the density and volume of an object, we now know how to calculate its weight using density and volume.

It's pretty straightforward to use the density to weight calculator by following these steps:

1. Input the density of the material, making first sure that the unit is correct. You can change the units by clicking on the unit and selecting from a wide range of density units. For example, you know that the object is made of lead, so you would enter 11,340 kg/m³ as the density.

2. Enter the volume of space that the object occupies. If you don't know the volume but do know the object's dimensions, expand the Calculate the volume section of the calculator to enter the object's length, width, and height. Let's say the lead artifact is 250 cm³.

3. And that's all there is to it. You now know the object's weight, which in our example is 2.835 kg.
