It is not always easy to convert densities, but it can be much easier with the right tools. Our density conversion converter is the perfect tool for any laboratory measuring different densities. Simply type in the numbers, and the calculator will do the work for you. This density conversion convector has the liquids, solids, and gases measurements. It can be used for conversion between different units of density.

What is Density

Density is a physical quantity characteristic of each substance. It is the ratio of the mass of a substance to its volume. If the density of a substance or body is equal at each point, the substance or body is homogeneous.

Density is typically measured in kilograms per cubic meter (kg/m3). The greater the density, the higher the concentration of the substance. 

You can use the formula below:

\rho = \frac{m}{V}

If a body is made up of several different substances, you cannot determine its density by knowing only the viscosity of those substances. In such cases, you can calculate the body’s density by dividing the total mass by the total volume of that body.

Density is not an invariant characteristic of a substance but depends primarily on temperature, which is valid for all substances in all aggregate states. For a gaseous state, the density strongly depends on the pressure in that gas. As a rule, the density of all substances decreases with increasing temperature.

Specific Gravity

Specific gravity is the size of the density of a substance. It is usually expressed as the ratio of the density of a substance to the density of water. A substance with a specific gravity of less than 1 is less dense than water and will float in it. A substance with a specific gravity greater than 1 is more viscous than water and will sink in it.

Density units, symbols, and conversion values table

The basic unit of density for solids is called the kilogram per cubic meter (kg/m3). But, we can also express density in other units of measurement. For example, if you want to find density in liquids, you need to use kg/L as a basic unit.

 How much density expressed in kg/m3 corresponds to the density expressed in g/cm3? Here is the result:


For the most commonly used bodies, the density is predetermined, and its amount can be found in the table below:

How to calculate density – example

Calculate the volume of the gold chain if its mass is 5.5 dag.
Use a table with body densities.

The mass of a gold chain is 5.5 dag or 55g.
From the table above, you can find that the gold density is 19300 kg/m3 or 19,3 g/cm3.
We can calculate the volume of the gold chain with this formula:

V = \frac{m}{\rho } = \frac{55}{19,3}=2,85cm^{3}

The density of water in lb/gal

Water is a chemical compound with a density of 1 gram per cubic centimeter. It is a clear, colorless, odorless, tasteless liquid essential for all living organisms. With very low viscosity, water is a good conductor of heat.

The basic unit for density of water is kg/m3, but you can also calculate it with lb/gal.

1 lb/gal = 119.826 kg/m3

The density of water in grams per cubic centimeters

We have already repeated several times that the basic unit of measurement for density is kg/m3. However, if we want to calculate the density of water in g/cm3, we will do it as follows:

The water temperature is 0°C, and the density is 999,839 kg/m3.
It is equal to 0,999839 g/cm3.


1. How do you convert density?

Density is equal to the mass of the body divided by its volume. So, if you want to convert density, you first need to find the body’s mass and volume.

2. What is the conversion factor of density?

You can use conversion factors for converting between different kinds of units. Also, you can use density as a conversion factor between body mass and body volume.

3. How do you convert density to kg/m3?

It is straightforward to convert from any unit into kg/m3. For example, if you need to convert density from 1 g/cm3 to kg/m3, you just need to divide 0,001kg with 0,000001m3. The result will be 1000kg/m3.
