Enter the mass of the substance (kg) and the specific gravity into the Volume from Specific Gravity Calculator. The calculator will evaluate and display the Volume from Specific Gravity. 

Volume from Specific Gravity Formula

The following formula is used to calculate the Volume from Specific Gravity. 

Vsg = m / (SG * 998.2 )
  • Where Vsg is the Volume from Specific Gravity (m^3)
  • m is the mass of the substance (kg) 
  • SG is the specific gravity 

To calculate volume from specific gravity, divide the mass of the substance by the result of the specific gravity times 998.2.

How to Calculate Volume from Specific Gravity?

The following example problems outline how to calculate Volume from Specific Gravity.

Example Problem #1:

  1. First, determine the mass of the substance (kg). 
    1. The mass of the substance (kg) is given as: 100.
  2. Next, determine the specific gravity. 
    1. The specific gravity is provided as: 20.
  3. Finally, calculate the Volume from Specific Gravity using the equation above: 

Vsg = m / (SG * 998.2 )

The values given above are inserted into the equation below:

Vsg = 100 / (20 * 998.2 ) = .00509 (m^3)

Example Problem #2: 

The variables needed for this problem are provided below:

mass of the substance (kg) = 400

specific gravity = 40

Entering these values and solving gives:

Vsg =400 / (40 * 998.2 ) = .01 (m^3)
