Actually having thought about it a lot, having fuel in the numerator avoids a lot of confusion. It makes the changes to the thing you are trying to conserve,gasoline, linear. I.e. when someone says "I only saved 5MPG with P&G", you can't quantify it. if they were getting 10mpg to start with, then they improved 50%!
For folks who drive mostly fixed commutes, it makes even more sense to put the distance in the denominator.
However, you can have it either way, without any programming. If you calibrate it for km instead of miles and liters instead of gallons, while it is NOT in metric mode, you will get the numbers you seek, though the labels will be a little off.
