Gravel Tons to Cubic Yards Calculator
Convert gravel weight to volume, or volume to weight, using the material density.
The conversion
- Cubic yards → tons: cubic yards × density
- Tons → cubic yards: tons ÷ density
Density is the only variable, and it is not fixed. Weight per cubic yard varies by gravel type, stone size, moisture content, compaction, and supplier-specific material. The defaults here are reasonable planning figures, not measured values for your load.
Default densities
| Material | Tons per cubic yard |
|---|---|
| General Gravel | 1.50 |
| Crushed Stone | 1.50 |
| Pea Gravel | 1.35 |
| River Rock | 1.20 |
| Limestone Gravel | 1.50 |
For purchasing decisions, use your supplier's published density when available. To start from dimensions, use the gravel calculator; to work backwards from material you already own, use the gravel coverage calculator.
