How to Convert Petrol / Gasoline from kg to Litres

To convert Petrol / Gasoline from kilograms to litres, divide the mass (in kg) by its density (0.745 kg/L).

Formula: Volume (L) = Mass (kg) ÷ Density (kg/L)
Example: 1 kg ÷ 0.745 kg/L = 1.342 Litres

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.

1

To Convert Kg to Litres

Divide the total weight in kilograms by the liquid density (ρ) in kg/L.

2

To Convert Litres to Kg

Multiply the total liquid volume in litres by the substance density (ρ) in kg/L.

Formula 1: Kilograms to Litres
Volume (L) = Mass (kg) ÷ Density (kg/L)

Where Volume is in Litres (L), Mass is in Kilograms (kg), and ρ (rho) is density in kg/L.

Formula 2: Litres to Kilograms
Mass (kg) = Volume (L) × Density (kg/L)

Example: 5 Litres of Olive Oil (ρ = 0.918 kg/L) = 5 × 0.918 = 4.59 kg.

Frequently Asked Questions

Is 1 kg equal to 1 litre?+
Only for water approximately (at 4°C, 1 kg = 1.000 litre). For other substances like Petrol / Gasoline, you need density (0.745 kg/L).
How many litres is 1 kg of Petrol / Gasoline?+
Using density 0.745 kg/L, 1 kg of Petrol / Gasoline is approximately 1.342 litres (1342 mL).
How do you convert kg to litres?+
Divide mass in kg by density in kg/L. Formula: Volume (L) = Mass (kg) ÷ Density (kg/L). For Petrol / Gasoline, divide mass in kg by 0.745.
How much does 1 litre of Petrol / Gasoline weigh in kg?+
1 litre of Petrol / Gasoline weighs approximately 0.745 kilograms (745 grams). Formula: Mass (kg) = Volume (L) × Density (kg/L).
