Gravel by Yard Calculator

Gravel Volume Formula:

\[ V = \frac{L \times W \times D}{27} \]

Gravel Volume (cu yd):

1. What is a Gravel by Yard Calculator?

Definition: This calculator estimates the volume of gravel needed based on the area's length, width, and depth in feet.

Purpose: It helps construction professionals and homeowners determine how much gravel is required for projects like driveways, walkways, or foundations.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \frac{L \times W \times D}{27} \]

Where:

\( V \) — Volume of gravel (cubic yards)
\( L \) — Length (feet)
\( W \) — Width (feet)
\( D \) — Depth (feet)
27 — Conversion factor (cubic feet per cubic yard)

Explanation: The calculator multiplies length × width × depth to get cubic feet, then divides by 27 to convert to cubic yards.

3. Importance of Gravel Volume Calculation

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

4. Using the Calculator

Tips: Measure the area's length and width in feet. For depth, typical gravel layers are 2-4 inches (convert to feet: 2" = 0.167', 4" = 0.333').

5. Frequently Asked Questions (FAQ)

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

Q2: What depth should I use?
A: For driveways use 4-6 inches, for walkways 2-3 inches. Convert inches to feet (divide by 12).

Q3: How do I measure irregular areas?
A: Break into rectangles, calculate each separately, then sum the volumes.

Q4: Does this include compaction?
A: No, consider adding 10-20% more gravel for compaction depending on material type.

Q5: How many tons is a cubic yard?
A: Typically 1.2-1.4 tons per cubic yard, but varies by material density.
