Different bulk materials have very different densities per volume.
Gravel and sand are much heavier per cubic yard than mulch, which is mostly organic and holds a lot of air.
The volume in cubic yards, from a materials calculator's result.
Use the cubic-yard result from the Gravel Driveway, Topsoil, or Mulch & Gravel calculators.
Estimated weight
13.5 tons
Actual density varies with moisture content and how tightly the material is compacted — wet or heavily-compacted material weighs more than this average-density estimate.
- Weight in pounds
- 27,000 lb

How this was calculated
Formula source(s)
- Commonly cited average bulk densities: gravel/sand ~2,700 lb/yd³ (1.35 tons), topsoil ~2,200 lb/yd³ (1.1 tons), mulch ~600 lb/yd³ (0.3 tons) — actual density varies by moisture content and compaction
Inputs used
- Material Type
- Gravel / crushed stone
- Volume
- 10
Intermediate steps
- Weight in pounds
- 27,000 lb
Confidence note: Actual density varies with moisture content and how tightly the material is compacted — wet or heavily-compacted material weighs more than this average-density estimate.
What this calculation does not cover
- Gravel and sand are given the same 2,700 lb per cubic yard here, so moving the selector between those two changes nothing at all. In a yard they are not one material — a dense crushed limestone runs heavier than that figure and a rounded washed stone or a dry fine sand lighter — and across a 20-yard order the spread over that real range runs to several tons, enough to change how many trucks the supplier sends.
