Density Converter
Density calculator: ρ = m/V. Find density, mass or volume in g/cm³, kg/m³, g/mL, lb/ft³ and more.
How to use this calculator
- Type the value you want to convert.
- Choose the unit you are converting from and the one you want.
- Read the result, or the full table of equivalent units below.
Density is mass per unit volume, ρ = m/V. Water has a density of about 1.000 g/cm³ at 4 °C, so objects with higher density sink in it.
Use it to identify materials, convert between mass and volume of a liquid, or check the purity of a sample.
Conversion formula
1 g/cm³ = 1 000 kg/m³ · 1 kg/m³ = 0.001 g/cm³
Common conversions: gram per cubic centimeter → kilogram per cubic meter
| g/cm³ | kg/m³ |
|---|---|
| 1 g/cm³ | 1 000 kg/m³ |
| 2 g/cm³ | 2 000 kg/m³ |
| 5 g/cm³ | 5 000 kg/m³ |
| 10 g/cm³ | 10 000 kg/m³ |
| 20 g/cm³ | 20 000 kg/m³ |
| 50 g/cm³ | 50 000 kg/m³ |
| 100 g/cm³ | 100 000 kg/m³ |
| 1 000 g/cm³ | 1 000 000 kg/m³ |
Frequently asked questions
What is the density of water?
About 0.9982 g/cm³ at 20 °C and 0.99997 g/cm³ at 4 °C.
