Forward Conversion
kg/m³ → g/cm³
Reverse Conversion
g/cm³ → kg/m³
Formula and Derivation
Relation between units:
- 1 kg = 1000 g
- 1 m = 100 cm ⇒ 1 m³ = 100³ cm³ = 1,000,000 cm³
Therefore:
g/cm³ = kg/m³ × (1000 g / 1 kg) × (1 m³ / 1,000,000 cm³) = kg/m³ × 0.001
kg/m³ = g/cm³ × 1000Example: 1000 kg/m³ → 1.000 g/cm³.

FAQs
What is the conversion factor from kg/m³ to g/cm³?
Multiply by 0.001 (or divide by 1000). The reverse conversion multiplies by 1000.
Why does 1 g/cm³ equal 1000 kg/m³?
Because 1 g is 1/1000 of a kilogram and 1 cm³ is 1/1,000,000 of a cubic meter. The ratios combine to 1000.
Does the calculator accept scientific notation?
Yes. You can type values like 1e3 or 7.85e3 and they will be parsed as numbers.
How should I choose decimal places or significant figures?
Match your measurement precision. For lab reporting, significant figures often align with instrument resolution.
Can I convert both directions?
Yes. Use the forward panel for kg/m³ to g/cm³ and the reverse panel for g/cm³ to kg/m³.
How do I share a specific result?
Use the Share link on the forward panel. It includes your inputs and rounding preferences in the URL.
Are example densities included?
Yes. Quick examples show water air and steel to help verify results.
