Coverage Calculator for Gravel

Coverage Formula:

\[ A = \frac{V \times 27}{D} \]

Area Covered (sq ft):

1. What is a Coverage Calculator for Gravel?

Definition: This calculator estimates the area that can be covered with gravel based on the volume of gravel available and the desired depth.

Purpose: It helps determine how much area a given amount of gravel will cover at a specified depth, useful for landscaping and construction projects.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ A = \frac{V \times 27}{D} \]

Where:

\( A \) — Area covered (square feet)
\( V \) — Volume of gravel (cubic yards)
\( 27 \) — Conversion factor (cubic feet per cubic yard)
\( D \) — Depth (feet)

Explanation: The gravel volume is converted to cubic feet, then divided by the depth (in feet) to determine coverage area.

3. Importance of Coverage Calculation

Details: Accurate coverage estimation ensures proper material planning, avoids shortages or excess, and helps with project budgeting.

4. Using the Calculator

Tips: Enter the gravel volume in cubic yards and desired depth in inches. The calculator automatically converts depth to feet for the calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is 27 used in the formula?
A: There are 27 cubic feet in 1 cubic yard (3 feet × 3 feet × 3 feet = 27 cubic feet).

Q2: What's a typical gravel depth for different applications?
A: Driveways typically use 4-6 inches, walkways 2-3 inches, and drainage layers 8-12 inches.

Q3: How does depth affect coverage?
A: Doubling the depth halves the coverage area, as you're spreading the same volume over a smaller area more thickly.

Q4: Can I use this for other materials like sand or mulch?
A: Yes, the formula works for any material where you know the volume and want to calculate coverage at a specific depth.

Q5: Should I account for compaction?
A: This calculator gives theoretical coverage. For compacted materials, consider adding 10-20% more material to your calculations.
