How to calculate gravel
The formula: tons = (length × width × depth⁄12) ÷ 27 × 1.4
- Measure the length and width in feet and the depth in inches.
- Multiply length × width × (depth ÷ 12) for cubic feet, then divide by 27 for cubic yards.
- Multiply cubic yards by 1.4 to estimate tons.
- A 2–3 inch depth is typical for paths; 4 inches for driveways.
