Formula and method

Cubic yards = length × width × depth/12 ÷ 27. Tons = cubic yards × density.

Example

A 50×10 ft area at 4 inches deep is about 6.17 cubic yards before compaction.

What this calculator is useful for

Estimate cubic yards and approximate tons of gravel from area and depth. It is designed for quick estimates and everyday problem solving.
