How do I convert g/cm3 to kg/m3?
Type a value in either box, and the answer shows it in the other unit as you type.
- Kilograms per cubic meter (kg/m³)
- 1,000
1 g/cm³ = 1,000 kg/m³.
Kilograms per cubic meter (kg/m³): 1,000. 1 g/cm³ = 1,000 kg/m³.
Kilograms per cubic meter (kg/m³) by grams per cubic centimeter (g/cm³)
How to calculate
Converts grams per cubic centimeter (g/cm³) to kilograms per cubic meter (kg/m³) and back, with the exact unit definitions.
Example with the default inputs (Grams per cubic centimeter (g/cm³) 1): 1 g/cm³ = 1,000 kg/m³.
Formula: kg/m³ = g/cm³ × 1000 (the same as g/cm³ ÷ 0.001)
- 1 gram per cubic centimeter = 1000 kilograms per cubic meter, from the exact definitions in NIST SP 811.
- Exact on the typed decimals: at most 6 decimal places (6 significant digits below 0.0001), rounded half up; an answer of 1 billion or more shows at most 15 significant digits.

- Kilograms per cubic meter (kg/m³) 2,700 gives Grams per cubic centimeter (g/cm³) 2.7.Source: Exact unit definitions in NIST SP 811 (2008), Appendix B.8
Other questions people ask
How many kilograms per cubic meter are in a gram per cubic centimeter?
1 gram per cubic centimeter is 1,000 kilograms per cubic meter, from the exact unit definitions (NIST SP 811).
How do I convert g/cm3 to kg/m3?
Multiply by 1,000: kg/m³ = g/cm³ × 1000 (the same as g/cm³ ÷ 0.001). For example, 1 g/cm³ × 1,000 = 1,000 kg/m³.
How do I convert kg/m3 back to g/cm3?
Multiply by 0.001, or type the kilograms per cubic meter into the second box and the converter works it out. 1 kilogram per cubic meter is 0.001 grams per cubic centimeter.
Is g/cm³ the same as g/mL?
Yes. A milliliter is a cubic centimeter (1 L = 1 dm³), so 1 g/cm³ = 1 g/mL = 1 kg/L = 1,000 kg/m³.
What is 1.5 g/cm³ in kg/m³?
1,500 kg/m³: 1.5 × 1,000. A gram is 0.001 kg and a cubic centimeter 0.000001 m³, so the factor is exactly 1,000.
