As noted above, the hours a plane flies is important. But there is another factor to measure, the number of cycles (takeoffs and landings). Here's why these are important.
Hours: The engines and other components wear by use. The longer the use, the more the wear. By convention and FAA rules, they must be torn down periodically and refurbished. Just like your car needs certain service at certain mileage.
Cycles: This is important for pressurized aircraft because of how they are made. Aluminium is a strong but light material, but it comes with a dangerous price. It fatigues. If you want to bend an aluminum bar many times, it will break from "metal fatigue". Steel doesn't do that as earily, but a steel plane won;t fly...too heavy. Therefore, they refurbish the skin and components after certain cycles because the pressurization of the plane kinda blows it up like a balloon, then it is relieved when landing. After a number of cycles, the skin would just fall off in fatigue cracks.

If you are asking if there is something similar to Miles per gallon in an aircraft, here is your answer: While the above answers are correct about hours and cycles, Mileage in an aircraft is measured in Nautical Miles Per Pound or NMPP. An aircraft manufacturer provides a performance manual which will provide a specific NMPP for a given speed (Mach number), altitude, and gross weight. This is used to find an aircraft's specific range.

on a 747 I have personally flown for 23 hours to Hong Kong so with some variables like head wind and weight you could probably fly 26 or more hours approximetly 9000 miles

The correct question is the number of hours on each component.

depends upon how much litre does it carry and how much heavy the plane is
