- What is density?
- How to calculate density from an object's mass (or weight).
- How to find mass given density and volume.

## What is density?

The density of an object is the amount of **mass per unit volume**. We can express it as:

where:

- $\rho$ — The
**density**of a substance; - $m$ — The
**mass (or weight)**of the substance; and - $V$ — The
**volume**of the substance.

Its SI unit is **kilograms per cubic meter** ($\text{kg}/\text{m}^3$), and imperial unit is **pounds per cubic feet** ($\text{lb}/\text{ft}^3$).

Using this equation, we can find:

- The density of the object from its mass and volume;
- The mass of the object from its density and volume; or
- The volume of the object from its density and mass.

## How to use this mass to density calculator

This mass to density calculator is easy to use and versatile. You can convert mass to density or density to mass, so long as you know the volume:

- To find
**density**, enter the object's**mass**and**volume**along with their units. - To find the
**mass**with density and volume, enter the object's**density**and**volume**and their units. - If you need to calculate the
**volume**of a**cuboidal object**at any step, simply use our`Calculate the volume`

option under the`Weight`

field of the calculator, and enter its dimensions!

### What is the density of the Earth?

**5.514 g/cm ^{3}** or

**0.1992 lb/in**. You can arrive at this answer through these steps:

^{3}- The
**mass**of the Earth is*5.97237 ×10*, and its^{24}kg**volume**is*1.08321 ×10*.^{12}km^{3} **Divide**the mass of the Earth by its volume to get its**density**,*5,514 ×10*, which is equal to^{-9}kg/km^{3}**5.514 g/cm**.^{3}- Congratulations, you've calculated the mean density of the Earth!

### How do you find mass from density and volume?

To find the mass of a substance with its density and volume, follow these steps:

**Multiply**the given**density**with the**volume**of the object.- The value we obtain in step 1 is the
**mass**of the object. You can verify your answer using our**mass to density calculator**.
