kg/m³ to kg/L Converter
Convert kilograms per cubic metre to kilograms per litre — divide by a thousand. Results update as you type; exact factors shown.
One kilogram per cubic metre is 0.001 kilogram per litre — see the exact factor, not a rounded rule of thumb.
How the kg/m³ to kg/l 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.
Australia is fully metric under the National Measurement Act 1960; imperial units appear only in trade with the US and in older documents.

FAQFrequently asked questions about density conversion
How many kg/m³ in a kg/L?
Exactly 1,000, because a cubic metre holds 1,000 litres.
What is water?
1,000 kg/m³, or 1 kg/L.
What is diesel?
About 850 kg/m³ — 0.85 kg/L.
Is kg/L the same as g/cm³?
Yes, numerically identical. Litres suit bulk liquids; cubic centimetres suit laboratory work.
What is mercury?
13,534 kg/m³, or 13.5 kg/L.
