How to calculate gravel

The formula: tons = (length × width × depth⁄12) ÷ 27 × 1.4

  1. Measure the length and width in feet and the depth in inches.
  2. Multiply length × width × (depth ÷ 12) for cubic feet, then divide by 27 for cubic yards.
  3. Multiply cubic yards by 1.4 to estimate tons.
  4. A 2–3 inch depth is typical for paths; 4 inches for driveways.
