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.
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 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.
