Jet A-1 Aviation Fuel weighs 0.804 kg per litre. Convert litres to kilograms (and back) using its exact density.
Quick Metrology Summary
1 liter of Jet A-1 Aviation Fuel weighs approximately 0.804 kilograms (or 804 grams) at standard room temperature. Because mass equals volume multiplied by density (\(m = V \times \rho\)), multiplying volume in liters by 0.804 gives the exact mass in kg.
Jet A-1 Aviation Fuel: Weight per Litre Explained
Jet A-1 Aviation Fuel has a density of 0.804 kg/L, which makes it 20% lighter than water. Jet A-1 is a tightly specified kerosene whose standard density range is 0.775–0.840 kg/L at 15°C. The typical working value is 0.804 kg/L.
When You Need This Conversion
Flight planning and weight-and-balance, where fuel uplift is ordered in litres but aircraft limits are in kilograms. Airlines routinely convert both ways.
What Changes the Density
Density changes with temperature roughly 0.00075 kg/L per °C, so cold fuel in winter weighs more per litre. Pilots and dispatchers use the density printed on the delivery ticket.

How to Convert Liters of Jet A-1 Aviation Fuel to Kilograms
Jet A-1 is a tightly specified kerosene whose standard density range is 0.775–0.840 kg/L at 15°C. The typical working value is 0.804 kg/L. To convert, multiply the volume in litres by 0.804. To go the other way, divide the weight in kilograms by 0.804.
kg = Litres × 0.804
L = kg ÷ 0.804
1 L → 0.804 kg
10 L → 8.04 kg
100 L → 80.4 kgExample
Convert 5 litres of jet a-1 aviation fuel to kilograms: 5 × 0.804 = 4.02 kg, or 8.86 lb. Reversed: 4.02 kg ÷ 0.804 = 5 L.
Worked examples
| Scenario | Calculation | Result |
|---|---|---|
| 1 L of jet a-1 aviation fuel | 1 × 0.804 kg/L | 0.804 kg |
| 5 L of jet a-1 aviation fuel | 5 × 0.804 kg/L | 4.02 kg |
| 20 L of jet a-1 aviation fuel | 20 × 0.804 kg/L | 16.08 kg |
| 100 L of jet a-1 aviation fuel | 100 × 0.804 kg/L | 80.4 kg |
| 10 kg of jet a-1 aviation fuel (reverse) | 10 ÷ 0.804 kg/L | 12.44 L |

Aircraft performance and take-off weight are calculated in mass. Fuel is delivered by volume, so the density on the delivery note is used to find kilograms.
At 0.804 kg/L, about 8,040 kg.
1 litre of jet a-1 aviation fuel weighs 0.804 kg (804 grams, or 1.77 lb), using a density of 0.804 kg/L.
1 kg of jet a-1 aviation fuel is 1.244 litres. Divide the weight by the density: 1 ÷ 0.804 = 1.244.
Multiply the volume by 0.804. For example, 10 litres of jet a-1 aviation fuel is 8.04 kg and 50 litres is 40.2 kg.
