1. What is a 3/8 Pea Gravel Calculator?

Definition: This calculator estimates the volume of 3/8" pea gravel needed based on the area dimensions (length, width, and depth).

Purpose: It helps homeowners and landscapers determine how much pea gravel is required for projects like pathways, driveways, or decorative landscaping.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

  • \( V \) — Volume of 3/8 pea gravel (cubic yards)
  • \( L \) — Length (feet)
  • \( W \) — Width (feet)
  • \( D \) — Depth (feet)
  • 27 — Cubic feet per cubic yard (conversion factor)

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

3. Importance of 3/8 Pea Gravel Calculation

Details: Proper pea gravel volume estimation ensures you purchase the right amount of material, avoiding costly overages or project delays from shortages.

4. Using the Calculator

Tips: Measure your project area carefully in feet. For depth, typical applications use 2-4 inches (convert to feet by dividing by 12).

5. Frequently Asked Questions (FAQ)

Q1: What's special about 3/8" pea gravel?
A: This size is ideal for walkways and decorative purposes as it's comfortable underfoot and provides good drainage.

Q2: How do I convert inches to feet for depth?
A: Divide inches by 12 (e.g., 3 inches = 0.25 feet).

Q3: Should I add extra for compaction?
A: Pea gravel doesn't compact significantly, but adding 5-10% extra is recommended for uneven surfaces.

Q4: How many cubic yards are in a ton of 3/8" pea gravel?
A: Typically about 1.4 tons per cubic yard, but this varies by material density.

Q5: What's the coverage per cubic yard?
A: One cubic yard covers about 100 sq ft at 3" depth, or 80 sq ft at 4" depth.
