📊 Common Material Densities
| Material | Density (kg/m³) | 1 m³ Weight | Notes |
|---|---|---|---|
| Water (pure) | 1,000 | 1 tonne | At 4°C, standard reference |
| Concrete | 2,400 | 2.4 tonnes | Standard reinforced |
| Gravel (dry) | 1,680 | 1.68 tonnes | Loose, dry |
| Sand (dry) | 1,600 | 1.6 tonnes | Loose, dry |
| Topsoil | 1,250 | 1.25 tonnes | Moist, uncompacted |
| Asphalt | 2,243 | 2.24 tonnes | Paving material |
| Steel | 7,850 | 7.85 tonnes | Carbon steel |
| Aluminum | 2,700 | 2.7 tonnes | Pure aluminum |
Note: Densities vary based on composition, moisture content, and compaction.
📚 Conversion Tips
Density Matters
Different materials have vastly different densities. Always verify the specific density for accurate conversions.
Temperature Effects
Density changes with temperature, especially for liquids and gases. Use appropriate density values for your conditions.
Material State
Compacted vs loose materials can have significantly different densities (e.g., gravel, soil).
Verify Units
Always double-check your units - mixing metric and imperial can lead to large errors.
Bulk Materials
For bulk materials like aggregates, account for void spaces which affect effective density.
Document Values
Record the density values used for future reference and consistency in calculations.
Note: This calculator provides estimates based on standard material densities. Actual weights may vary due to material composition, moisture content, compaction, and other factors. Always verify with material specifications when precise calculations are required.
