Determine the weight of 867 US Gallons of fuel (SG 0.78).

  • A

    2560 lbs

  • B

    5361 lbs

  • C

    5635 lbs

  • D

    8122 lbs

Convert USG into litres, litres into kilograms and finally kilograms into pounds:
US Gallons to Litres (l) => Litres = US Gal × 3.785

867 USG x 3.785 = 3281.6 l

Conversion between Fuel volume and mass: Fuel volume in litres x Specific Gravity (density) = Fuel Mass in Kg

3281.9 l x 0.78 = 2559.6 kg

Kilograms (kg) to Pounds (Lbs) => Lbs = Kilograms x 2.205

2 559.9 kg x 2.205 = 5645 lb


Alternatively,
On your flight computer, align 867 on the inner scale with the US Gal index on the outer scale. Look up to 0.78 on the Sp G (lbs) index on the outer scale.
Read 5650 lb on the inner scale.

  • Closest option: 5635 lb
