1. What is a 3/4 Crushed Gravel Calculator?

Definition: This calculator estimates the volume of 3/4" crushed gravel needed based on the area dimensions and desired depth.

Purpose: It helps construction professionals and DIYers determine how much 3/4" crushed gravel is required for projects like driveways, walkways, and drainage systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of gravel (cubic yards)
• \( L \) — Length (feet)
• \( W \) — Width (feet)
• \( D \) — Depth (feet, converted from inches)
• 27 — Cubic feet per cubic yard conversion factor

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

3. Importance of 3/4" Crushed Gravel

Details: 3/4" crushed gravel is ideal for drainage, base material, and decorative purposes. Proper volume estimation ensures proper coverage and cost-effective material purchasing.

4. Using the Calculator

Tips: Enter the length and width in feet, and depth in inches. All values must be > 0. The depth is automatically converted from inches to feet in the calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is depth entered in inches but calculated in feet?
A: Most gravel depth measurements are specified in inches (e.g., 4" base), but the calculation requires feet, so the conversion happens automatically.

Q2: What's the typical depth for different applications?
A: Driveways: 4-6", Walkways: 2-3", Drainage: 6-12". Adjust based on your specific needs.

Q3: How much does 3/4" crushed gravel weigh?
A: Approximately 1.25-1.35 tons per cubic yard, depending on moisture content and material composition.

Q4: Does this include compaction factor?
A: No, consider adding 10-20% to the calculated volume for compaction, especially for base materials.

Q5: How do I convert cubic yards to tons?
A: Multiply cubic yards by 1.3 (average weight) to get approximate tons needed.
