Example Material Densities
Use these common bulk densities as starting points. Adjust per supplier.
| Material | Density (kg/m³) | Density (lb/ft³) |
|---|---|---|
| Crushed stone / gravel | 1600 | 99.9 |
| Sand (dry) | 1600 | 99.9 |
| Soil (loose) | 1200 | 74.9 |
| Concrete | 2400 | 149.9 |
| Water | 1000 | 62.43 |
| Asphalt mix | 2320 | 144.8 |
| Limestone (crushed) | 1550 | 96.7 |
| Steel (solid) | 7850 | 489.5 |
| Timber (average) | 600 | 37.5 |
Formula Used
The calculator converts inputs to volume (m³) or mass (kg) then to tonnes/tons:
Volume mode:
mass_dry (kg) = volume (m³) × density (kg/m³)Area × thickness mode:
volume (m³) = area × thickness (units converted)Mass mode:
mass_dry (kg) = entered mass (kg)Adjustments:
mass_adj = mass_dry × (1 + moisture%) × (1 + waste%) × (1 + compaction%)Conversions:
t = kg ÷ 1000,
short ton = kg ÷ 907.18474,
long ton = kg ÷ 1016.0469088

FAQs
A metric tonne (t) is 1000 kg. A short ton (US) is 2000 lb (≈907.18 kg). A long ton (UK) is 2240 lb (≈1016.05 kg).
Start with a typical bulk density from the table, then adjust for grading, moisture, and supplier data. Different quarries and moisture states vary widely.
Moisture increases wet mass. Waste accounts for losses during transport or placement. The calculator multiplies both factors, so totals rise accordingly.
Yes. Choose “Area × Thickness”; the tool converts to volume internally, then applies density to compute mass and tonnage.
Suppliers quote proprietary blends, gradations, and moisture contents. Use their stated density and recommended factors for purchase orders.
If you specify compacted thickness, more material may be needed to account for void reduction. The compaction factor models that increase.
Yes. Use CSV/PDF export or create a shareable URL from your current scenario to review with teammates.
