# True porosity Calculator English Español

True porosity is the ratio of the volume of the open pores to the bulk volume of the material expressed as a percentage between 0% to 100%. Porosity is the measurement of the empty or void space in a material. It is the fraction of void(empty space) volume to total volume. This True porosity calculator is used to determine the true magnitude of open porosity. Enter the apparent solid specific gravity (Ga) and true specific gravity (Gt) to calculate the true porosity.

## True porosity Calculation

True porosity is the ratio of the volume of the open pores to the bulk volume of the material expressed as a percentage between 0% to 100%. Porosity is the measurement of the empty or void space in a material. It is the fraction of void(empty space) volume to total volume. This True porosity calculator is used to determine the true magnitude of open porosity. Enter the apparent solid specific gravity (Ga) and true specific gravity (Gt) to calculate the true porosity.

Code to add this calci to your website  #### Formula:

True porosity = ( 1 - ( Ga / Gt ) ) x 100 ) Where, Ga - Apparent Solid Specific Gravity Gt - True Specific Gravity

### Example:

Calculate the true porosity of a sample with the apparent solid specific gravity of 30 and true specific gravity of 35.

#### Solution:

True porosity = ( 1 - ( 30 / 35 ) ) x 100 )
= 14.2857
