Gravel Calculator
Rectangular pit volume from length, width, and depth; gravel type presets for density; weight and cost from price per tonne or per cubic yard.
Choose a gravel type (or custom density), enter the pad or trench footprint and fill depth, and get volume, mass, and optional total cost from price per mass or per volume.
Default regular gravel density is about 1680 kg/m³—adjust for your supplier and add extra for compaction and waste.
