1. What is the 3/4 Inch Crushed Stone Calculator?

The 3/4 Inch Crushed Stone Calculator estimates the quantity of crushed stone needed for a project in tons based on the length, width, and depth of the area to be covered.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( length \) — Length in feet
• \( width \) — Width in feet
• \( depth \) — Depth in feet
• 27 — Conversion factor (cubic feet to cubic yards)
• 1.4 — Weight conversion factor (cubic yards to tons)

Explanation: The equation first calculates cubic yards by dividing cubic feet by 27, then converts to tons by multiplying by 1.4 (the approximate weight of 3/4" crushed stone per cubic yard).

3. Importance of Accurate Calculation

Details: Accurate calculation helps in proper project planning, budgeting, and ensures you order the correct amount of material - avoiding both shortages and excess.

4. Using the Calculator

Tips: Measure the length and width of your project area in feet. For depth, consider the recommended depth for your specific application (typically 2-4 inches for walkways, 4-6 inches for driveways).

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 1.4?
A: 1.4 is the approximate weight (in tons) of one cubic yard of 3/4" crushed stone. This accounts for material density.

Q2: What's the typical depth for different applications?
A: Walkways: 2-4 inches, Driveways: 4-6 inches, Patios: 4 inches, Drainage: 6-12 inches.

Q3: Should I order extra material?
A: It's recommended to order 10-15% extra to account for compaction, uneven surfaces, and spillage.

Q4: How does compaction affect the calculation?
A: The calculation accounts for typical compaction. For projects requiring heavy compaction, consider adding 10% to your total.

Q5: Can this be used for other stone sizes?
A: This calculator is specifically for 3/4" crushed stone. Other materials may have different weight factors.
