The direct answer: a cubic yard is a volume (3 feet by 3 feet by 3 feet); a ton is a weight (2,000 pounds). How many tons are in a cubic yard depends entirely on the material: dense crushed stone runs about 1.4 to 1.5 tons per yard, sand is similar, and topsoil is closer to 1 ton per yard. Moisture moves those numbers too; a yard of sand after a rainstorm weighs noticeably more than a dry one.
Why both units exist
Landscapers and homeowners think in cubic yards because projects are measured in volume: how many yards to fill a bed, top a driveway, or level a yard. Quarries and truckers think in tons because trucks are limited by weight, not volume. A dump truck might legally haul 18 tons, which is roughly 12 to 13 yards of stone but 16-plus yards of topsoil. When a supplier quotes per ton and your project is measured in yards, you need the conversion to compare apples to apples.
Rough conversions for common materials
| Material | Tons per cubic yard (approx.) | Yards per ton (approx.) |
|---|---|---|
| Crushed stone (#57, crusher run, drain rock) | 1.4 to 1.5 | 0.67 to 0.71 |
| Limerock base | 1.4 to 1.6 | 0.63 to 0.71 |
| Sand (mason, concrete, fill) | 1.3 to 1.5 | 0.67 to 0.77 |
| Topsoil / soil blends | 1.0 to 1.2 | 0.83 to 1.0 |
| Rip rap | 1.3 to 1.5 | 0.67 to 0.77 |
These are working approximations, not lab values. Moisture, gradation, and how settled the pile is all shift the real number. For ordering purposes they are close enough; for engineering work, use certified weights.
The conversion math
Tons to yards: divide tons by the tons-per-yard figure. Ten tons of #57 stone at 1.4 tons per yard is about 7.1 yards.
Yards to tons: multiply yards by the tons-per-yard figure. Eight yards of topsoil at 1.1 tons per yard is about 8.8 tons, well within a single truckload.
When in doubt, round the material side up: running short mid-project costs more than the extra half yard.
Why it matters for delivery
Truck capacity is the practical reason this matters. Our trucks are weight-limited, so a "full load" of dense stone is fewer yards than a full load of topsoil. When you request a quote, give us the material and the project dimensions; we will translate that into the right number of loads. Our material calculator estimates yards from length, width, and depth, and shows a rough tonnage alongside.
