Pico hectares are a good unit of area to use for this. For a car that gets N miles/gallon, for 1/N gallons/mile, that works out to 235/N pico hectares.

That results in nice small, but not too small, numbers for most current cars, around 50 pico hectares for a Humvee in the city to around 4 pico hectares for a Prius on the highway.

Square centimeters or millimeters seem easier to visualise. The area represents the size of the tube that feeds the engine to get this mileage. You could even express it in the form of a radius.

I cannot really find a standard definition of pico hectares, but am I correct in assuming we're talking about 0.01 mm²? Or 1 square hecto-micrometre, I guess.
