1. What is a Gravel Weight Calculator?

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

Purpose: It helps determine how much gravel is 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)

Explanation: The formula calculates volume (A × D), converts to weight (× ρ), then converts pounds to tons (÷ 2000).

3. Importance of Gravel Weight Calculation

Details: Accurate calculations ensure proper material ordering, cost estimation, and project 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.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical gravel density?
A: Most gravel has a density between 100-130 lb/ft³. The default is 100 lb/ft³ for general calculations.

Q2: How do I measure the area?
A: For rectangular areas: length × width. For circular areas: π × radius². For irregular shapes, break into smaller rectangles.

Q3: What depth should I use?
A: Typical depths: 2-4 inches for walkways (convert to feet), 4-6 inches for driveways, 1 inch for decorative purposes.

Q4: Why divide by 2000?
A: There are 2000 pounds in 1 ton, so we convert the final weight from pounds to tons.

Q5: Does this include waste or overage?
A: No, consider adding 5-15% to the calculated weight for compaction and project contingencies.
