Supply Math| Material | Tons per yd³ | Yd³ per ton | Yd³ in 10 tons |
|---|---|---|---|
| Crushed stone (#57) | 1.5 | 0.67 | 6.7 |
| Pea gravel | 1.4 | 0.71 | 7.1 |
| River rock | 1.4 | 0.71 | 7.1 |
| Road base / crusher run | 1.6 | 0.63 | 6.3 |
| Sand | 1.35 | 0.74 | 7.4 |
These are typical dry weights. Moisture and stone size change them, so ask your supplier for their figure and use it in the gravel calculator.
