Miles per gallon measurements don't work that well for airplanes.
After all, there's factors like the plane's headwind or tailwind
speed,

airplanes are usually figured at
gallons/hour consumption.

Yes, we all know that, but approximations (meaningful ones) can still be
made. Yes, you would have to figure with no headwind, and direct route, (or
airways for big stuff) and you would do the same for the ground
transportation. Reality would be different, but that is beside the point.

Figure fuel used for a round trip to a destination far enough away to allow
getting to cruise altitude, then figure gas mileage for a car for the same
destination, and there you have it.
