A gallon of aviation fuel weighs approximately 6.1 pounds

Aviation fuel density varies by type, but standard jet fuel (Jet A) typically weighs around 6.1 pounds per gallon. This weight impacts aircraft loading, fuel calculations, and operational efficiency.

Weight Variations by Fuel Type

  • Jet A fuel: 6.1 pounds per gallon
  • Jet A-1 fuel: 6.1-6.3 pounds per gallon
  • Aviation gasoline (Avgas): 5.8-5.9 pounds per gallon

Factors Affecting Weight

Temperature: Fuel expands and contracts with temperature changes Altitude: Density decreases at higher altitudes Composition: Different fuel blends affect overall weight

Comparison of Fuel Weights

Fuel TypeWeight per GallonTypical Density
Jet A6.1 lbs0.79 g/cm³
Jet A-16.1-6.3 lbs0.80 g/cm³
Avgas5.8-5.9 lbs0.72 g/cm³

Practical Applications

  • Pilot fuel calculations require precise weight measurements
  • Aircraft loading protocols depend on accurate fuel weights
  • Ground operations use weight data for proper handling
