Gravel calculator
Estimate gravel for driveways, paths or pads. Returns cubic yards, tons and cost.
Short answer: cu yd = (L × W × depth/12) ÷ 27. Tons = cu yd × 1.4 (typical gravel). 30 × 10 ft × 4" = 3.7 cu yd ≈ 5.2 tons. Enter your measurements above and the gravel calculator returns the quantity, unit conversions and an estimated cost instantly, in imperial or metric — no sign-up needed.
