LPG (Liquid Petroleum Gas) weighs 0.54 kg per litre. Convert litres to kilograms (and back) using its exact density.
Quick Metrology Summary
1 liter of LPG (Liquid Petroleum Gas) weighs approximately 0.54 kilograms (or 540 grams) at standard room temperature. Because mass equals volume multiplied by density (\(m = V \times \rho\)), multiplying volume in liters by 0.54 gives the exact mass in kg.
LPG (Liquid Petroleum Gas): Weight per Litre Explained
LPG (Liquid Petroleum Gas) has a density of 0.54 kg/L, which makes it 46% lighter than water. Liquefied petroleum gas is stored under pressure as a liquid. As a butane/propane mixture it weighs about 0.54 kg/L — nearly half the weight of water.
When You Need This Conversion
Domestic cylinders, forklift and camping gas, autogas tanks in vehicles and bulk delivery to rural properties.
What Changes the Density
Propane-heavy winter blends are lighter, near 0.50 kg/L, and butane-heavy summer mixes approach 0.57. Cylinders are only filled to about 80–85% of their volume for safety.
How it works

How to Convert Liters of LPG (Liquid Petroleum Gas) to Kilograms
Liquefied petroleum gas is stored under pressure as a liquid. As a butane/propane mixture it weighs about 0.54 kg/L — nearly half the weight of water. To convert, multiply the volume in litres by 0.54. To go the other way, divide the weight in kilograms by 0.54.
kg = Litres × 0.54
L = kg ÷ 0.54
1 L → 0.54 kg
10 L → 5.4 kg
100 L → 54 kgExample
Convert 5 litres of lpg (liquid petroleum gas) to kilograms: 5 × 0.54 = 2.7 kg, or 5.95 lb. Reversed: 2.7 kg ÷ 0.54 = 5 L.
Worked examples
| Scenario | Calculation | Result |
|---|---|---|
| 1 L of lpg (liquid petroleum gas) | 1 × 0.54 kg/L | 0.54 kg |
| 5 L of lpg (liquid petroleum gas) | 5 × 0.54 kg/L | 2.7 kg |
| 20 L of lpg (liquid petroleum gas) | 20 × 0.54 kg/L | 10.8 kg |
| 100 L of lpg (liquid petroleum gas) | 100 × 0.54 kg/L | 54 kg |
| 10 kg of lpg (liquid petroleum gas) (reverse) | 10 ÷ 0.54 kg/L | 18.52 L |

Autogas tanks are filled to about 80%, so ~32 L of liquid × 0.54 ≈ 17.3 kg.
Because the liquid expands and the pressure changes with temperature, volume is unreliable. Weight is constant.
1 litre of lpg (liquid petroleum gas) weighs 0.54 kg (540 grams, or 1.19 lb), using a density of 0.54 kg/L.
1 kg of lpg (liquid petroleum gas) is 1.852 litres. Divide the weight by the density: 1 ÷ 0.54 = 1.852.
Multiply the volume by 0.54. For example, 10 litres of lpg (liquid petroleum gas) is 5.4 kg and 50 litres is 27 kg.
