How to Convert Kilograms to Litres
Converting mass (kilograms) to liquid volume (litres) is not a direct 1:1 ratio for every liquid. While 1 kg of pure water equals exactly 1 litre (at 4°C), other substances possess distinct mass densities due to their molecular structures.
To Convert Kg to Litres
Divide the total weight in kilograms by the liquid density (ρ) in kg/L.
To Convert Litres to Kg
Multiply the total liquid volume in litres by the substance density (ρ) in kg/L.
Where Volume is in Litres (L), Mass is in Kilograms (kg), and ρ (rho) is density in kg/L.
Example: 5 Litres of Olive Oil (ρ = 0.918 kg/L) = 5 × 0.918 = 4.59 kg.
