Sorry, but I never never said it was metric vs imperial. The emphasis was on mpg vs gallons per 100miles if you prefer it this way. The first one is good for ad

Sorry, but I never never said it was metric vs imperial. The emphasis was on mpg vs gallons per 100miles if you prefer it this way. The first one is good for advertisers the other one for truly understanding how much your travel costs you. (Yes, you can do a division instead of multiplication as pointed out but ask an average Joe how much a trip costs him)
