How to convert density
Density is mass per unit volume. Water is about 1 g/cm³ (1,000 kg/m³), which makes g/cm³ and kg/L convenient reference units for liquids and solids.
Every density unit is a fixed multiple of one base unit, the kg/m³. To convert a value, multiply it by the size of the starting unit and divide by the size of the target unit. For example, to convert g/cm³ to kg/m³, multiply by 1,000. To go the other way, divide by 1,000.
The converter above does this for you and shows the exact formula under the result.

Frequently asked questions
What is the density of water?
Pure water is about 1 g/cm³ (1,000 kg/m³) at 4 °C. At room temperature it is slightly less, about 0.998 g/cm³.
How do I convert g/cm³ to kg/m³?
Multiply the value in g/cm³ by 1,000 to get kg/m³. For example, 10 g/cm³ = 10,000 kg/m³.
How many kg/m³ is 1 g/cm³?
1 g/cm³ = 1,000 kg/m³, and 1 kg/m³ = 0.001 g/cm³.
