Enter the void volume and the total volume into the Porosity Calculator. The calculator will evaluate the Porosity.

## Porosity Formula

The following two example problems outline the steps and information needed to calculate the Porosity.

P = Vv / Vt

Variables:

- P is the Porosity (void:total)
- Vv is the void volume
- Vt is the total volume

To calculate the porosity, divide the void volume by the total volume.

## How to Calculate Porosity?

The following steps outline how to calculate the Porosity.

- First, determine the void volume.
- Next, determine the total volume.
- Next, gather the formula from above = P = Vv / Vt.
- Finally, calculate the Porosity.
- 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.

void volume = 30

total volume = 100

P = Vv / Vt** **= ?
