1. What is a Gravel Tonnage Calculator?

Definition: This calculator estimates the weight of gravel in tons based on volume and material density.

Purpose: It helps construction professionals and DIYers determine how many tons of gravel are needed for projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Weight of gravel (tons)
• \( V \) — Volume of gravel (cubic feet)
• \( \rho \) — Density of gravel (pounds per cubic foot)

Explanation: The volume is multiplied by density to get pounds, then divided by 2000 to convert to tons.

3. Importance of Gravel Tonnage Calculation

Details: Accurate tonnage estimation ensures proper material ordering, cost control, and project planning.

4. Using the Calculator

Tips: Enter the gravel volume in cubic feet and density (default 110 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 100-120 lb/ft³, with 110 lb/ft³ being a common average.

Q2: Why divide by 2000?
A: There are 2000 pounds in a ton, so this converts the weight from pounds to tons.

Q3: How do I find the gravel volume?
A: Measure length × width × depth in feet, or use our Gravel Volume Calculator.

Q4: When would I change the density value?
A: Adjust for different materials (e.g., 95 lb/ft³ for pea gravel, 125 lb/ft³ for crushed stone).

Q5: Does this include waste or overage?
A: No, consider adding 5-10% to the calculated tonnage for project contingencies.
