What is the fuel consumption of an 747?

The fuel consumption of a Boeing 747 varies depending on the specific model and flight conditions, but on average, it consumes about 10 to 11 tons (approximately 8,000 to 9,000 liters or 2,100 to 2,400 gallons) of fuel per hour. For long-haul flights, this translates to around 4,000 to 5,000 nautical miles range, consuming roughly 0.25 to 0.30 miles per gallon. Factors such as weight, weather, and flight altitude can significantly impact fuel efficiency.
