What does this tool do?
Gravel is ordered by volume or tonnage, and the two are linked by bulk density. This calculator turns length, width and depth into cubic yards and tons, then prices the order.
The Formula
Volume (yd³) = length × width × depth(in) ÷ 12 ÷ 27; tons = volume × density (t/yd³)Frequently Asked Questions
How deep should gravel be?
About 2 to 3 inches for a decorative bed or path and 4 to 6 inches for a driveway base, depending on the subsoil and expected traffic.
How many tons are in a cubic yard?
Roughly 1.4 tons for gravel and 1.5 tons for crushed stone, though moisture and stone size change the figure. Confirm the density with your supplier.
