1. What is Pea Gravel?

Pea gravel is small, rounded stones typically about 1/4" to 1/2" in diameter. It's commonly used for landscaping, pathways, and drainage projects due to its smooth texture and attractive appearance.

2. How the Calculator Works

The calculator uses these formulas:

Where:

• \( length \) — Length of area in feet
• \( width \) — Width of area in feet
• \( depth \) — Depth of gravel layer in feet
• 110 lbs/ft³ — Standard density of pea gravel

Explanation: The calculation first determines the volume in cubic feet, then converts to weight using the standard density of pea gravel.

3. Importance of Accurate Calculation

Details: Accurate calculations ensure you purchase the right amount of gravel, avoiding costly over-ordering or project delays from under-ordering.

4. Using the Calculator

Tips: Measure your area carefully in feet. For depth, consider both the desired depth and any compaction that will occur (typically add 10-20% for compaction).
