The metric aspect doesn't matter.
What "bcjohnso99" was saying, is that mpg empasizes the MILES as the variable - if I get better fuel economy, I get more MILES to a gallon.
If you rate fuel economy as gallons per 100 miles (gallons per mile would be a fraction) then the emphasis is on the fuel used - if I get better fuel economy, I need less fuel to drive the same distance.
If you compare two vehicles, the miles you can go per a set amount of fuel matters less than the fuel used over a set distance. Because I have a certain SET distance I need to drive. To work, to school, to the store, etc....those distances don't change if I get better fuel economy, the fuel used DOES.
mpg is an INDIRECT measurement of fuel economy.
gp100m is a DIRECT measurement of fuel economy.
