40 Cubic Yards of Crushed Stone in Tons
40 cubic yards of crushed stone in tons works out to about 56.0 tons using a planning weight of 1.4 tons per yard. Real loads land between roughly 54.0 and 60.0 tons depending on stone size, fines and moisture. That is about 112,000 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 40 × 1.4 = 56.0 tons.
- Low end: 40 × 1.35 = 54.0 tons.
- High end: 40 × 1.5 = 60.0 tons.
If your supplier quotes a different weight per yard, multiply by theirs.

About crushed stone
Crushed stone has fractured faces, so the pieces interlock when compacted. That is why it holds a driveway or pad shape better than round stone of the same size.
Hauling 40 yards
Plan the delivery around 56.0 tons: two or more trucks in most areas. A pickup is a poor fit for anything past a fraction of a yard; see how much gravel a half-ton pickup can carry.
Before you order
- Confirm whether the yard prices crushed stone by the ton or by the yard.
- Add about 10 percent for compaction and uneven ground.
- Clear a firm spot for the truck to dump.
The volume and tonnage calculator converts any area and depth into yards and tons.
Where crushed stone fits
Works well for:
- Driveway top courses and parking pads
- Shed and hot tub bases
- Backfill behind walls when a clean size is used
Poor fit for:
- Barefoot areas, since angular stone is rough
- Play areas
- Places that need a smooth rolling surface for wheels
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of crushed stone (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 20x25 area at 2 inches takes about 4.3 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
