1. What is Gravel Coverage Calculator?

Definition: This calculator estimates the area that can be covered with gravel based on project dimensions and material density.

Purpose: It helps determine how much area a given amount of gravel will cover for driveways, walkways, or other projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( A \) — Area covered (square feet)
• \( L \) — Length (feet)
• \( W \) — Width (feet)
• \( D \) — Depth (feet)
• \( T \) — Tons per cubic yard

Explanation: The formula calculates the volume of space to be filled with gravel and divides by the material density to determine coverage area.

3. Importance of Gravel Coverage Calculation

Details: Accurate coverage calculations ensure you purchase the right amount of material, preventing project delays and budget overruns.

4. Using the Calculator

Tips: Enter the project dimensions in feet and the gravel density (default 1.4 tons/cu yd). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical value for tons per cubic yard?
A: Most gravel weighs about 1.4 tons per cubic yard, but this can vary based on material type and moisture content.

Q2: How do I convert inches to feet for depth?
A: Divide inches by 12 (e.g., 3 inches = 0.25 feet).

Q3: Does this account for compaction?
A: No, for compacted gravel, consider increasing the depth by 20-30% in your calculations.

Q4: How do I calculate for circular areas?
A: Use (π × radius² × depth) instead of length × width, then divide by tons per cubic yard.

Q5: Should I order extra gravel?
A: Yes, it's recommended to add 10-15% to your calculated amount for waste and uneven surfaces.
