Rock Coverage per Ton

Rock Coverage Formula:

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

Coverage Area (sq ft):

1. What is Rock Coverage per Ton Calculator?

Definition: This calculator estimates the area that can be covered by a given weight of rock based on its density and desired depth.

Purpose: It helps landscapers and construction professionals determine how much area a certain amount of rock will cover at a specified depth.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

\( A \) — Area covered (square feet)
\( T \) — Tons of rock
\( D \) — Density of rock (tons/cubic yard)
27 — Cubic feet per cubic yard conversion
Depth — Desired depth in inches (converted to feet in calculation)

Explanation: The tons are converted to cubic yards using density, then converted to cubic feet, and finally divided by depth to get coverage area.

3. Importance of Rock Coverage Calculation

Details: Accurate coverage estimation ensures proper material ordering, cost control, and project planning for landscaping and construction projects.

4. Using the Calculator

Tips: Enter the tons of rock, rock density (default 1.25 tons/cu yd), and desired depth in inches (default 3"). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical rock density?
A: Most landscape rock weighs about 1.25 tons per cubic yard, but this varies by material type (e.g., lava rock is lighter, granite is heavier).

Q2: How does depth affect coverage?
A: Doubling the depth halves the coverage area. A 3" depth is common for most landscaping applications.

Q3: What if I want coverage in square yards?
A: Divide the square footage result by 9 to convert to square yards.

Q4: Does this account for compaction?
A: No, consider adding 10-15% more material if significant compaction is expected.

Q5: How do I measure irregular areas?
A: Break the area into simple shapes (rectangles, circles) and calculate each separately, then sum the results.
