Density Calculator
Select and enter the values to calculate the density and other related variables available in the density formula.
Density Calculator
Calculate the density of an object or a substance, where density is the mass per unit of volume. With this density calculator, you can find any of the three variables in the density equation by providing the other two.
Density:
If volume \(V\) and mass \(M\) are given, then density is:
\[ \rho = \frac{M}{V} \]
Volume:
If density \(\rho\) and mass \(M\) are given, then volume is:
\[ V = \frac{M}{\rho} \]
Mass:
If volume \(V\) and density \(\rho\) are given, then mass is:
\[ M = \rho \times V \]
Density (\(\rho\)) Formula:
The density formula is:
\[ \rho = \frac{M}{V} \]
Density determines how much mass is closely packed together in a given unit of volume. When two objects have the same volume, the denser one will have more mass than the other one.
Common Density (ρ) Units
As the density is a scalar quantity and the SI unit of density is kg/m³. But in the case of solid, we use g/cm³ for convenience to indicate density, while liquid and gases are determined in g/ml and g/L respectively. However, other units are given below:
| Other Units | Conversion of Various Units of Density to the SI unit kg/m³ |
| Gram per cubic centimeter | = 1000 kilograms per cubic meter |
| Gram per cubic meter | 0.001 |
| Kilogram per liter | 1000 |
| Gram per liter | 1 |
| Pound per cubic inch | 27,680 |
| Pound per cubic foot | 16.02 |
| Pound per cubic yard | 0.5933 |
| Pound per gallon (US) | 119.83 |
| Pound per gallon (UK) | 99.78 |
| Ounce per cubic inch | 1,730 |
| Ounce per cubic foot | 1.001 |
| Ounce per gallon (US) | 7.489 |
| Ounce per gallon (UK) | 6.236 |
| Ton (short) per cubic yard | 1,186.60 |
| Ton (long) per cubic yard | 1,328.90 |
Example:
- Gold is a dense metal, which is why it's so valuable
- Styrofoam is a very low-density material that is used for insulation
- Gasoline is less dense than water, therefore in oil spills it floats on the top of water
- Air is less dense than most solids and liquids
- Ice is less dense than the water due to why ice floats on above surface of water
