Enter the total volume (gallons) and the total area (in^2) into the Calculator. The calculator will evaluate the Gallons Per Square Inch.

## Gallons Per Square Inch Formula

GSI = G / A

Variables:

- GSI is the Gallons Per Square Inch (gallons/in^2)
- G is the total volume (gallons)
- A is the total area (in^2)

To calculate Gallons Per Square Inch, divide the volume in gallons by the area in square inches.

## How to Calculate Gallons Per Square Inch?

The following steps outline how to calculate the Gallons Per Square Inch.

- First, determine the total volume (gallons).
- Next, determine the total area (in^2).
- Next, gather the formula from above = GSI = G / A.
- Finally, calculate the Gallons Per Square Inch.
- 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 (gallons) = 8000

total area (in^2) = 2000
