1. What is the Easy Gravel Calculator?

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

Purpose: It helps homeowners and contractors quickly determine how much gravel is required for landscaping or construction 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 layer (feet)
• \( \rho \) — Density of gravel (pounds per cubic foot)

Explanation: The formula calculates volume in cubic feet, converts to weight in pounds, then converts to tons by dividing by 2000.

3. Importance of Accurate Gravel Calculation

Details: Proper gravel estimation prevents over-ordering (saving money) or under-ordering (preventing project delays).

4. Using the Calculator

Tips: Enter the area in square feet, depth in feet, and density (default 110 lb/ft³). Typical densities range from 100-130 lb/ft³.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure the area?
A: For rectangular areas, multiply length × width. For circular areas, use π × radius².

Q2: What depth should I use?
A: For driveways use 4-6 inches (0.33-0.5 ft), for walkways use 2-3 inches (0.17-0.25 ft).

Q3: Why does density matter?
A: Heavier gravel (higher density) provides better compaction but requires more weight for the same volume.

Q4: How many tons are in a cubic yard?
A: About 1.4 tons per cubic yard (varies by material). Our calculator gives direct weight in tons.

Q5: Should I add extra for compaction?
A: Yes, add 10-15% to your total if compacting the gravel for stability.
