Density Calculator
Compute the density of objects with ease
Calculate Density
About This Calculator
This Density Calculator helps you determine the density of an object by dividing its mass by its volume. It’s a fundamental concept in physics and engineering, useful for identifying materials and understanding their properties.
Use this tool to make quick and accurate density calculations for various applications.
Density Calculator
The density of a material, typically denoted using the Greek symbol ρ, is defined as its mass per unit volume.
| ρ = | m V | where:ρ is the density m is the mass V is the volume |
Density is easy to calculate. The units used for density calculations, however, require particular attention. Density can be expressed in a variety of ways, and an incorrect value will arise if the appropriate units are not used or converted. It is helpful to thoroughly document all of the values being worked with, including units, and to carry out dimensional analysis to make sure that the outcome contains units of
volume of mass. Keep in mind that temperature and pressure also have an impact on density. Usually, there is little change in density between solids and liquids. However, temperature and pressure have a significant impact on density when discussing gases. As pressure rises, volume falls and density always rises. Since volume usually increases with temperature, density tends to decrease. However, there are some exceptions, such as when water's density rises from 0°C to 4°C.
The densities of some common materials are listed below, along with a table of units commonly used to express density.
