Gravel Coverage Calculator by Tons of Concrete

Gravel Coverage Calculator

Gravel Coverage Formula:

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

Coverage Area (sq ft):

1. What is a Gravel Coverage Calculator?

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

Purpose: It helps determine how much area can be covered with a given amount of gravel at a specific 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:

\( A \) — Coverage area (square feet)
\( V \) — Gravel volume (cubic yards)
\( 27 \) — Conversion factor (cubic feet per cubic yard)
\( D \) — Depth of coverage (feet)

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

3. Importance of Gravel 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 coverage depth in inches. All values must be > 0.

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).

Q2: What's a typical gravel coverage depth?
A: For driveways, 4-6 inches is common. For walkways, 2-3 inches. For drainage, 8-12 inches may be needed.

Q3: How does depth affect coverage?
A: Doubling the depth halves the coverage area. For example, 1 cubic yard covers 54 sq ft at 6" depth or 108 sq ft at 3" depth.

Q4: Does this account for compaction?
A: No, consider adding 10-20% more gravel if significant compaction is expected.

Q5: How do I convert from tons to cubic yards?
A: Use our Gravel Calculator by Tons tool or divide tons by density (typically 1.4 tons/cu yd for gravel).
