1. What is a Pea Gravel Calculator?

Definition: This calculator estimates the volume of pea gravel needed based on the area dimensions and desired depth.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of pea gravel (cubic yards)
• \( L \) — Length of area (feet)
• \( W \) — Width of area (feet)
• \( D \) — Depth of gravel (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 Accurate Calculation

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

4. Using the Calculator

Tips: Measure your area's length and width in feet. Enter depth in inches (calculator converts to feet). 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, the standard measurement for bulk materials.

Q2: What's the typical depth for pea gravel?
A: For walkways, 2-3 inches; for driveways, 4-6 inches; for decorative cover, 1-2 inches.

Q3: How do I measure irregular areas?
A: Break into rectangles, calculate each separately, then sum the volumes.

Q4: Does this account for compaction?
A: No, consider adding 10-15% to the calculated volume for compaction.

Q5: How many bags equal a cubic yard?
A: Typically 40-50 bags (0.5 cu ft each) make 1 cubic yard, but check bag labels.
