Enter the total number of holes and the total area (in^2) into the Calculator. The calculator will evaluate the Holes Per Square Inch.

## Holes Per Square Inch Formula

HSI = H / SI

Variables:

- HIS is the Holes Per Square Inch (holes/in^2)
- H is the total number of holes
- SI is the total area (in^2)

To calculate Holes Per Square Inch, divide the total number of holes by the total area.

## How to Calculate Holes Per Square Inch?

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

- First, determine the total number of holes.
- Next, determine the total area (in^2).
- Next, gather the formula from above = HSI = H / SI.
- Finally, calculate the Holes 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 number of holes = 60

total area (in^2) = 30
