## The Formula: Acres to Square Feet

The basic formula for converting acres to square feet is straightforward:

**Formula:**`acresToSquareFeet = (acres) => acres * 43560`

In this formula:

`acres`

is the area in acres that you want to convert to square feet.`squareFeet`

is the resulting area in square feet.

### Why 43,560?

The number 43,560 might seem arbitrary, but it has historical roots. An acre was originally defined as the amount of land tillable by one man behind an ox in one day. Through various systems and standards, it became defined as 4,840 square yards, which equals 43,560 square feet. This fixed measurement is now widely accepted and used.

## Inputs and Outputs

For clarity, let's define our inputs and outputs:

**Input:***acres*– The area in acres (e.g., 1 acre, 2.5 acres, etc.).**Output:***squareFeet*– The area in square feet (e.g., 43,560 square feet for 1 acre).

## Example Calculation

Let's take a real world example. Suppose you own a small plot of land that is 2 acres and you want to know the area in square feet:

- Using the formula:
`acresToSquareFeet = (acres) => acres * 43560`

- Plugging in the values:
`acresToSquareFeet(2) => 2 * 43560`

- The result: 87,120 square feet.

Therefore, 2 acres equal 87,120 square feet.

## Data Validation

When performing any calculation, it's essential to ensure the inputs are valid. For this formula, the input should be:
