How the conversion works

Weight and volume are linked by density: how many grams one millilitre of something weighs. Water is 1 g/mL, so 1 kg of water is exactly 1 litre. For anything else, pick the substance.

L = kg × 1 (water)

1 kg = 1 L

Why 1 kg isn't always 1 litre

Oil is lighter than water, so 1 kg of cooking oil takes up about 1.09 litres. Honey is heavier, so 1 kg of honey is only about 0.70 litres.

Typical densities

Densities change a little with temperature and brand. The values here are typical; for exact work, use the density printed on the product or its data sheet.

For water, 1 mL weighs 1 gram. For other substances, multiply millilitres by the density in g/mL.

How do I convert litres of petrol to kg?
