Enter the total volume of voids and the total volume of the soil into the Void Ratio Calculator. The calculator will evaluate and display the Void Ratio.

## Void Ratio Formula

The following formula is used to calculate the Void Ratio.

n = VV / VS *100

• Where n is the Void Ratio (%)
• VV is the total volume of voids
• VS is the total volume of the soil

## How to Calculate Void Ratio?

The following example problems outline how to calculate Void Ratio.

Example Problem #1:

1. First, determine the total volume of voids.
• The total volume of voids is given as: 40.
2. Next, determine the total volume of the soil.
• The total volume of the soil is provided as: 80.
3. Finally, calculate the Void Ratio using the equation above:

n = VV / VS *100

The values given above are inserted into the equation below and the solution is calculated:

n = 40 / 80 *100 = 50 (%)

Example Problem #2:

For this problem, the variables required are provided below:

total volume of voids = 80

total volume of the soil = 90

Test your knowledge using the equation and check your answer with the calculator above.

n = VV / VS *100 = ?
