Specific Volume Calculator


About Specific Volume Calculator (Formula)

A Specific Volume Calculator is a tool used to determine the specific volume of a substance, which represents the amount of volume occupied by a unit mass of that substance. It’s commonly used in fluid dynamics, thermodynamics, and engineering to characterize the properties of materials. The formula to calculate specific volume is as follows:

Specific Volume (v) = Volume (V) / Mass (m)


  • Volume (V): The amount of space occupied by the substance.
  • Mass (m): The quantity of the substance.

By dividing the volume by the mass, you can calculate the specific volume, which is usually expressed in units such as cubic meters per kilogram (m³/kg) or liters per gram (L/g).

For example, if you have a volume of 0.5 cubic meters and a mass of 2 kilograms, the specific volume would be:

Specific Volume (v) = 0.5 m³ / 2 kg = 0.25 m³/kg

This means that each kilogram of the substance occupies 0.25 cubic meters of volume.

The Specific Volume Calculator is particularly useful in fluid dynamics, where it helps understand how much space a given mass of fluid occupies. It’s also relevant in thermodynamics when analyzing the properties of gases and liquids under varying conditions of temperature and pressure.

It’s important to note that specific volume can change with changes in pressure and temperature for gases, so this value is typically reported under specific conditions. Additionally, specific volume is inversely proportional to density; substances with higher densities have lower specific volumes, and vice versa.
