How the calculation works

Cubic yards = length × width × depth in feet ÷ 27; tons = yards × density.

Example

A 30×4-foot path at 4 inches deep needs about 1.56 yd³ or 2.18 tons at 1.4 tons/yd³.

When to use this calculator

Use it for base stone, decorative gravel, drainage rock, and compacted fill estimates.
