This tool helps you calculate the amount of crushed rock needed for your project.

## How to Use the Crushed Rock Calculator

To use the calculator, follow these steps:

- Enter the length of the area in feet.
- Enter the width of the area in feet.
- Enter the depth of the area in inches.
- Optionally, enter the density of the crushed rock in pounds per cubic foot. If unknown, leave the default value.
- Click the “Calculate” button.
- The result will be displayed in tons.

## How the Calculator Works

The calculator computes the volume of the area in cubic feet based on the entered length, width, and depth. The depth in inches is converted to feet because one foot equals 12 inches. The formula used is:

Volume (cubic feet) = Length (feet) × Width (feet) × Depth (inches) / 12Then, the volume is multiplied by the density of the crushed rock (in pounds per cubic foot) to get the total weight in pounds.

Finally, the weight is converted to tons (1 ton = 2000 pounds). The formula used for this conversion is:

Weight (tons) = (Volume (cubic feet) × Density (pounds per cubic foot)) / 2000

## Limitations

This calculator provides an estimation and may not account for all factors such as:

- Variations in density of the crushed rock.
- Uneven surfaces or true depth variations.
- Compaction and settling of material over time.
