A plane like a Boeing 747 uses approximately 1 gallon of fuel (about 4 liters) every second. Over the course of a 10-hour flight, it might burn 36,000 gallons (150,000 liters). According to Boeing's Web site, the 747 burns approximately 5 gallons of fuel per mile (12 liters per kilometer). This sounds like a tremendously poor miles-per-gallon rating! But consider that a 747 can carry as many as 568 people.
jet fuel is not sold by the gallon, but by weight. it is also measured un weight when loaded on an aircraft, as it makes the weight and balance calculations easier. fuel burn is also calculated in lbs per hour. as for the weight of the fuel, it runs about 6lbs per gallon.
