Gravel by Yard Calculator Square Feet to Tons

Gravel Weight Formula:

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

Gravel Weight (tons):

1. What is a Gravel by Yard Calculator?

Definition: This calculator converts area measurements in square feet to gravel weight in tons based on depth and material density.

Purpose: It helps estimate how many tons of gravel are needed to cover a specific area at a desired depth.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

\( T \) — Weight of gravel (tons)
\( A \) — Area to cover (square feet)
\( D \) — Depth of gravel (feet)
\( D_g \) — Density of gravel (tons/cubic yard)

Explanation: The formula converts square feet to cubic yards (dividing by 27) and then multiplies by density to get weight.

3. Importance of Gravel Weight Calculation

Details: Accurate weight estimation ensures proper material ordering, transportation planning, and structural support calculations.

4. Using the Calculator

Tips: Enter the area in square feet, desired depth in inches or feet (consistent units), and gravel density (default 1.4 tons/cu yd).

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 27 in the formula?
A: There are 27 cubic feet in 1 cubic yard (3 feet x 3 feet x 3 feet).

Q2: What's a typical gravel density?
A: Most gravel weighs about 1.4 tons per cubic yard, but this varies by material type (1.2-1.6 tons/cu yd range).

Q3: How do I convert inches to feet for depth?
A: Divide inches by 12 (e.g., 6 inches = 0.5 feet).

Q4: Can I use this for other materials?
A: Yes, just adjust the density value (e.g., sand ~1.2 tons/cu yd, crushed stone ~1.6 tons/cu yd).

Q5: Does this account for compaction?
A: No, consider increasing depth by 20-30% if significant compaction is expected.
