Specific Volume Calculator

Simply enter the density of materials in the specific volume calculator and click calculate to find the specific volume.

kg/m3

Specific volume calculator finds a special type of volume, aka specific volume, using the density of the liquids. You can also find density by entering the specific volume. This means it works both ways.

What is specific volume?

The specific volume of liquids refers to a unit mass of material. It is the volume (in cubic meters) occupied by one kilogram. The SI unit for specific volume is m3kg-1.

specific volume

Experimentally, Specific volume can be measured through the displacement of liquids.

For this purpose, hydrometers are used. This displacement is divided by weight afterward to calculate the specific volume.

Specific volume formula

Specific volume is simply reciprocal of the density of the material. It is calculated by the equation:

V = 1/ρ

Where, ρ is the symbol used to represent density. 

How to calculate the specific volume?

Example

Find the specific volume of water at 20 degrees.

Solution:

Step 1: Write the density of the material.

ρ of water = 998.3 kgm-3            

Step 2: Find the reciprocal of the density.

ρ = 1 / 998.3

ρ = 0.001 kgm-3
