Calculate density
Enter the mass (g) and volume (cm³ or mL). The tool computes ρ = m/V in g/cm³ and converts it to kg/m³.
Reference values
- Water ≈ 1 g/cm³
- Aluminium ≈ 2.7 g/cm³
- Iron ≈ 7.87 g/cm³
- Gold ≈ 19.3 g/cm³
Example
| Input | Value |
|---|---|
| Mass | 100 g |
| Volume | 50 cm³ |
| Density | 2 g/cm³ |
| In kg/m³ | 2000 kg/m³ |

Frequently asked questions
What is the density formula?
ρ = mass ÷ volume. E.g. 100 g ÷ 50 cm³ = 2 g/cm³.
How to convert g/cm³ to kg/m³?
Multiply by 1000: 1 g/cm³ = 1000 kg/m³. The tool shows both.
Density vs specific gravity?
Density has units (kg/m³). Specific gravity is unitless (ratio to water).
What is the density of water?
About 1 g/cm³ (1000 kg/m³) at 4 °C.
