Convert bulk landscape materials between weight and volume — gravel, sand, topsoil and mulch — using typical per-yard densities you can adjust to match your supplier.

—

Densities are typical loose, dry weights. Moisture, compaction and stone size change them, so use your supplier’s stated density when you have one.

Common conversions

Material1 ton ≈1 cubic yard ≈
Gravel / crushed stone0.71 yd³1.40 tons
Sand0.77 yd³1.30 tons
Topsoil0.91 yd³1.10 tons
Mulch, dry4.00 yd³0.25 tons
Mulch, wet2.50 yd³0.40 tons
Crushed concrete0.69 yd³1.45 tons

How the conversion works

Weight and volume are linked by density. In reverse:
cubic yards = tons ÷ (tons per cubic yard)
tons = cubic yards × (tons per cubic yard)
One cubic yard is 27 cubic feet — a box 3 ft × 3 ft × 3 ft.

There is no single correct density for a material. Wet sand weighs more than dry sand; compacted gravel weighs more per yard than loose delivery. The densities above are typical loose delivery values for estimating, and the number to trust is the one your supplier quotes.

Which number should you order

Order in the unit your supplier sells in — bulk aggregates are often sold by the ton, while delivered soil and mulch are often sold by the yard. If your project needs a volume first, start with the gravel, topsoil or mulch calculator, then convert to the supplier’s unit here. Remember that quoted depths usually refer to compacted material, and spreading takes more volume than the finished layer.
