What does this tool do?
Gravel is ordered by weight, but sold by volume in many yards. This calculator multiplies length, width and depth to get cubic yards, then applies a typical bulk density to estimate tons.
The Formula
Tons = Length × Width × Depth ÷ 12 ÷ 27 × Density (tons per cu yd)Frequently Asked Questions
How many tons is a cubic yard of gravel?
About 1.4 tons for crushed stone and 1.45 tons for pea gravel, depending on moisture.
How deep should gravel be?
4 in is common for driveways after compaction and 2 in for paths; compact in layers for anything deeper.
