Enter the total volume and the solid volume into the calculator to determine the void volume. This calculator helps in finding the volume of space not occupied by solid material.

Void Volume Formula

The following formula is used to calculate the void volume.

VV = TV - SV

Variables:

  • VV is the void volume (mL)
  • TV is the total volume (mL)
  • SV is the solid volume (mL)

To calculate the void volume, subtract the solid volume from the total volume.

What is Void Volume?

Void volume is the volume of the empty space in a container or material that is not occupied by solid matter. It is a critical parameter in materials science, geology, and various engineering fields. The void volume can affect the flow of fluids through materials, the strength of structures, and the storage capacity of containers.

How to Calculate Void Volume?

The following steps outline how to calculate the Void Volume.


  1. First, determine the total volume (TV) in milliliters (mL).
  2. Next, determine the solid volume (SV) in milliliters (mL).
  3. Use the formula VV = TV – SV to calculate the void volume (VV).
  4. Finally, calculate the Void Volume (VV) in milliliters (mL).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Total Volume (TV) = 500 mL

Solid Volume (SV) = 300 mL
