kg/m³ to g/cm³ Converter
Convert kilograms per cubic metre to grams per cubic centimetre — divide by a thousand. Results update as you type; exact factors shown.
One kilogram per cubic metre is 0.001 gram per cubic centimetre — see the exact factor, not a rounded rule of thumb.
How the kg/m³ to g/cm³ converter works
Density converts through kg/m³. 1 g/cm³ = 1 kg/L = 1,000 kg/m³ (water at 4 °C). 1 lb/ft³ = 16.0185 kg/m³ and 1 lb/US gal = 119.83 kg/m³. Concrete is about 2,400 kg/m³, steel 7,850 kg/m³, petrol about 740 kg/m³.
The UK is metric for most trade and science but keeps miles, pints, stone and mpg (with the imperial gallon) in daily life.

FAQFrequently asked questions about density conversion
How many kg/m³ is 1 g/cm³?
1,000 kg/m³.
What is the density of water?
1,000 kg/m³, or 1.000 g/cm³ — which is how the units were designed.
What is the density of steel?
About 7,850 kg/m³, or 7.85 g/cm³.
Why two units for the same thing?
Engineering uses kg/m³ for SI consistency; chemistry prefers g/cm³ because typical values land near 1.
What is the density of ice?
917 kg/m³ — lower than water, which is why it floats.
