1. What is the Gravel Weight Calculator?

Definition: This calculator estimates the weight of gravel needed based on area, depth, and material density.

Purpose: It helps determine how many tons of gravel are required for landscaping, construction, or drainage projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Weight of gravel (tons)
• \( A \) — Area to cover (square feet)
• \( D \) — Depth of gravel (feet)
• \( \rho \) — Density of gravel (pounds per cubic foot, typically 100-130)

Explanation: The formula calculates volume in cubic feet, converts to weight in pounds, then converts to tons (2000 lbs = 1 ton).

3. Importance of Gravel Weight Calculation

Details: Accurate weight estimation ensures proper material ordering, structural support, and budget planning.

4. Using the Calculator

Tips: Enter the area in square feet, depth in feet, and density (default 100 lb/ft³). All values must be > 0, with density between 100-130.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical gravel density?
A: Most gravel ranges from 100-130 lb/ft³. Lighter materials like pea gravel are ~100 lb/ft³, while crushed stone is ~130 lb/ft³.

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

Q3: Why divide by 2000 in the formula?
A: This converts pounds to tons (1 ton = 2000 pounds).

Q4: How accurate is this calculation?
A: It provides a good estimate but actual needs may vary based on compaction and material variations.

Q5: Should I add extra for waste?
A: Yes, consider adding 5-10% to the calculated amount for project contingencies.
