1. What is a Cubic Yard of Stone Calculator?

Definition: This calculator estimates the volume of stone needed in cubic yards based on length, width, and depth measurements in feet.

Purpose: It helps construction professionals and DIYers determine how much stone is required for landscaping, foundations, or other projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The length, width, and depth are multiplied to get cubic feet, then divided by 27 to convert to cubic yards.

3. Importance of Stone Volume Calculation

Details: Accurate stone volume estimation ensures proper material ordering, minimizes waste, and helps with project budgeting.

4. Using the Calculator

Tips: Measure the area's length and width in feet, then determine the desired depth of stone. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 27?
A: There are 27 cubic feet in 1 cubic yard, so dividing by 27 converts cubic feet to cubic yards.

Q2: How do I measure irregular areas?
A: Break the area into rectangular sections, calculate each separately, then sum the volumes.

Q3: What depth should I use?
A: For walkways use 2-3 inches, for driveways 4-6 inches. Convert inches to feet (divide by 12).

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

Q5: How many tons is a cubic yard of stone?
A: Typically 1.2-1.5 tons per cubic yard, depending on stone type and density.
