Sand, gravel: m³ ↔ tonnes ↔ bulk bags
The classic mistake: ordering tonnes while thinking in volumes. 1 m³ of gravel weighs about 1.5 tonnes — and 1 tonne of gravel is only ≈ 0.65 m³. This converter uses the real densities of delivered aggregates.

| ⚖️ Weight | |
| 🛍️ Bulk bags (≈ 1 m³) |
Average densities for dry to slightly damp aggregates. Wet sand can weigh up to 15% more: if your quantities are tight, order one step up.
Key figures
| Material | 1 m³ weighs | 1 tonne equals |
|---|---|---|
| Sand | ≈ 1.6 t | ≈ 0.63 m³ |
| Gravel | ≈ 1.5 t | ≈ 0.65 m³ |
| Concrete mix | ≈ 1.55 t | ≈ 0.65 m³ |
