An online density calculator allows you to find the density of a substance that is equal to its mass per unit volume. Also, if you are looking for a way to calculate density of the object by the category & name of the material, then this density finder best way to go!

So, here you get brief knowledge regarding how to find density, its formula, and a little more for your understanding.

Also, you can try our online momentum calculator that helps you to find the momentum of the moving object as well as determine the mass of the object.

Read on!

The density of a substance is referred to as its mass per unit volume. More precisely, it is said to be as the volumetric mass density; also called specific mass. Mostly, the symbol that is used to represent density is \(\rho\) (the lower case Greek letter rho), although sometimes the Latin letter \(D\) can also be considered. For the mathematical representation of density, you have to look at the given formula.

Remember that density is typically expressed in units of grams per cubic centimeter. For example:

- The density of water is equal to \(1\) gram per cubic centimeter
- The earth density is equal to \(5.51\) grams per cubic centimeter

Also, density can be expressed as kilograms per cubic meter (in meter-kilogram-second or SI units). For example:

- The density of air is expressed as \(1.2\) kilograms per cubic meter.

However, you can find that densities of some common solids, liquids, and gases are listed in textbooks and handbooks. Also, our density calculator helps you to find the densities of some common substances within a fraction of seconds.

Calculating density is not too complex as it seems, it’s very simple. Just put the values in the given density equation to easily compute any of the variables you want:

$$ \rho = \frac {m}{V} $$

Where,

\(\rho\) = density

\(V\) = volume

\(m\) = mass

If you want to find volume with density and mass, then the density calculator uses the formula:

$$ V = \frac {m}{\rho} $$

To find mass with density and volume, consider the following formula:

$$ m = \rho \times V $$

The density can be defined as mass per unit volume of the object. With the values, enter the units of measurements and this calculator will convert among the units.

No doubt, density calculator is the best way to measure the density of any substance. But, if you want to check your sample problems by hand, then you can calculate density by entering the values into the density formula. Here we have an example for each calculation:

Swipe on!

**Example: **

The object has weighed about \(150\) \(g\) and volume of \(90\) \(cm^3\). Find the density of object?

**Solution:**

The formula is:

\(\rho = \frac {m}{V}\)

Here,

\(m = 150 g\)

\(V = 90 cm^3\)

So,

\(\rho = \frac {150}{90}\)

\(\rho = 1.66 gcm^-3\)

You can readily find the volume of an object by rearranging the density equation. Let’s have a look at the example:

**Example:**

What a body have volume, if its mass is \(500 g\) & density of \(4cm^-3\)?

**Solution:**

The formula is:

\(V = \frac {m}{\rho}\)

Here,

\(m = 500 g\)

\(\rho = 4cm^-3\)

So,

\(V = \frac {500}{4}\)

\(V = 125 cm^3\)

The calculations of mass from volume & density become easy. Simply follow the example as follow:

**Example:**

The volume of object is \(200cm^3\) and the density is \(9 cm^-3\), what is the mass of object?

**Solution:**

The formula is:

\(m = \rho \times V\)

Here,

\(V = 200 cm^3\)

\(\rho = 9 cm^-3\)

So,

\(m = (9) \times (200)\)

\(m = 1800 g\)

The density of water between \(0 °C\) and \(4 °C\) is generally \(100kg/m^3\), but it changes with the temperature. As the temperature increases, the volume of material increases. As from the formula, the volume & density are inversely related to each other, ultimately the density of material decreases. The density of water at different temperatures is given in the table follow:

200°F/93.3°C | 0.96333 | 60.135 |
