    Jet Fuel Converter

    Convert jet fuel between litres, gallons, kilograms and pounds, using the fuel's density.

    Which fuel?
    kg/L. Use the figure on your fuel receipt for an exact uplift.

    How your fuel is converted

    Everything goes through litres: mass = litres × density.

    1. 1

      Start in litres

      10,000 L entered
      → 10,000 L

    2. 2

      Times the density

      10,000 L × 0.800
      = 8,000 kg

    3. 3

      Kilograms to pounds

      8,000 kg ÷ 0.4536
      = 17,637 lb

    4. 4

      Litres to gallons

      10,000 L ÷ 3.785
      = 2,642 US gal
      10,000 L ÷ 4.546
      = 2,200 imp gal

    Fuel is ordered and delivered by volume but planned by weight. Density links the two, and it changes with fuel type and temperature.

    mass (kg) = volume (L) × density (kg/L)

    Worked example

    An uplift of 10,000 L of Jet A-1 at 0.800 kg/L weighs 10,000 × 0.800 = 8,000 kg, which is 17,637 lb.

    Typical densities

    Jet A-10.800 kg/LSpecification range 0.775–0.840 kg/L at 15 °C
    Jet A0.803 kg/LCommon US planning figure of 6.7 lb per US gallon
    Avgas 100LL0.719 kg/LCommon planning figure of 6.0 lb per US gallon

    Unit factors used

    1 US gallon = 3.785411784 L · 1 imperial gallon = 4.54609 L · 1 lb = 0.45359237 kg.
