Kilograms per cubic metre to Grams per cubic centimetre Converter kg/m³ → g/cm³

1 kilogram per cubic metre (kg/m³) = 0.001 grams per cubic centimetre (g/cm³). Type a value below — the conversion happens instantly, entirely on your device.

From

1 kg/m³ = 0.001 g/cm³

Precision

1000 kilograms per cubic metre = 1 grams per cubic centimetre

1000 × 0.001 = 1

1 kg/m³ equals 0.001 g/cm³, so multiplying by 0.001 converts the value. The result describes the exact same quantity — only the measuring stick changes.

How to convert kilograms per cubic metre to grams per cubic centimetre

grams per cubic centimetre = kilograms per cubic metre × 0.001 — multiply the kilogram per cubic metre value by 0.001.

Example: 1000 kg/m³ = 1 g/cm³.

To convert the other way: kilograms per cubic metre = grams per cubic centimetre ÷ 0.001 — or use the dedicated g/cm³ to kg/m³ converter .

Kilograms per cubic metre to grams per cubic centimetre divides by 1,000: water at 1,000 kg/m³ is exactly 1 g/cm³. Because water is the reference, g/cm³ values double as "times denser than water" (aluminium 2.7, steel ~7.85).
