Porosity Formula

Output: Press calculate

Formula:P = (Vv / Vb) × 100%

Introduction to Porosity Formula

The porosity of a material is a measure of the void spaces in a material, and is calculated by dividing the void or pore volume by the total volume of the material, and then multiplying by 100 to get a percentage.

Parameters usage:

Example valid values:


Data validation

The voidVolume and bulkVolume should be greater than zero. The result is a percentage representing the porosity of the material.


This porosity calculator helps in determining the extent of void spaces within a material and expresses it as a percentage of the total volume.
