How this calculator works
Gravel volume converted to tons with delivery cost estimate. Planning estimates only — verify measurements and local codes on site. Cu yd = L × W × (depth in ÷ 12) ÷ 27; tons ≈ cu yd × 1.4. Example: 40×12 ft driveway, 4 in gravel → ~2.4 cu yd, ~3.4 tons.
Cu yd = L × W × (depth in ÷ 12) ÷ 27; tons ≈ cu yd × 1.4.
Example: 40×12 ft driveway, 4 in gravel → ~2.4 cu yd, ~3.4 tons.
