1. What is the Crushed Stone Calculator?

The Crushed Stone Calculator estimates the volume of crushed stone needed in cubic yards based on the length, width, and depth of the area to be covered. It's essential for landscaping and construction projects.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Length \) — Length of the area in feet
• \( Width \) — Width of the area in feet
• \( Depth \) — Depth of the stone layer in feet
• 27 — Conversion factor (1 cubic yard = 27 cubic feet)

Explanation: The formula converts cubic feet to cubic yards by dividing by 27, giving you the amount of crushed stone needed for your project.

3. Importance of Accurate Calculation

Details: Accurate calculation helps prevent over-ordering (wasting money) or under-ordering (delaying your project) crushed stone for your landscaping or construction needs.

4. Using the Calculator

Tips: Measure the length and width of your area in feet. Determine your desired depth (typically 2-4 inches for walkways, 4-6 inches for driveways). Convert depth to feet (divide inches by 12) before entering.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert inches to feet for depth?
A: Divide inches by 12. For example, 3 inches = 0.25 feet (3 ÷ 12 = 0.25).

Q2: Should I order extra crushed stone?
A: It's recommended to order 10-15% extra to account for compaction and spillage during spreading.

Q3: What's the typical depth for different projects?
A: Walkways: 2-4 inches, Driveways: 4-6 inches, Patios: 4-6 inches, Drainage: 6-12 inches.

Q4: How much does a cubic yard of crushed stone weigh?
A: Typically 2,400-2,900 lbs depending on stone type. Check with your supplier for exact weights.

Q5: Can I use this for other materials like mulch or topsoil?
A: Yes, the same formula works for any bulk material measured in cubic yards.
