Density Calculator
Please provide any two values to the fields below to calculate the third value in the density equation of
| ρ = | m |
| V |
The density of a material, typically denoted using the Greek symbol ρ, is defined as its mass per unit volume.
| ρ = |
|
where:
ρ is the density m is the mass V is the volume |
The calculation of density is quite straightforward. However, it is important to pay special attention to the units used for density calculations. There are many different ways to express density, and not using or converting into the proper units will result in an incorrect value. It is useful to carefully write out whatever values are being worked with, including units, and perform dimensional analysis to ensure that the final result has units of
| mass |
| volume |
Below is a table of units in which density is commonly expressed, as well as the densities of some common materials.
