A Boeing 747 gets about 0.2 miles per gallon (just under 1 kilometer per liter). This may sound like a gas guzzler, but if you fill a 747 to 3/4 of its passenger capacity, it is actually more fuel efficient than a passenger car with a driver and one passenger. This, of course, is in terms of fuel used per passenger.
Fun flight facts:
A Boeing 747 holds about 63,705 gallons (241,140 liters) of gas.
It takes about 12,755 gallons (48,283 liters) of gas to fly from Los Angeles to Honolulu.
Total flights flown on all 747s together add up to about 42 billion nautical miles (77.8 billion km), or 101,500 trips to the moon and back.
3.5 billion people, more than half of the world's population, have flown on a 747.
Take-off speed is about 180 miles per hour (290 km/hr); the airplane lands at about 160 miles per hour (260 km/hr).
Discussion Comments
Other sources say that a Boeing 747 gets upto 5 MPG... Which is equivalent to 2 km per liter.
1 mi/gal = 0.42 km/L
0.2 mpg is about 0.085km/liter, so the tweet at the top is off by over an order of magnitude
