Mpg

Abbreviation for Miles per gallon, as a measure of fuel consumption. The U.S. gallon is 3.785 liters. The Imperial gallon is 20% larger (4.546 liters). When a vehicle gets 30 mpg (US), he will get 36 mpg (Imperial). The metric system calculates fuel consumption as the number of liters per 100 kilometers. The same vehicle will be giving 7.8 l/100 km.

MPG shortfall

The difference between actual on-road MPG and EPA laboratory test MPG. MPG shortfall is expressed as gallons per mile ratio (GPMR).

Mph

Abbreviation for miles per hour. The metric equivalent is Kilometers per hour (kph). To convert Miles to Kilometers, multiply by 1.609344. It may be easier to divide the miles by 10 (i.e., knock off a zero) and then double it four times. Thus 60 mph divided by 10 is 6. Doubled is 12, doubled is 24, doubled is 48, doubled is 96. The accurate figure is 96.56, but 96 is probably close enough. To convert from Kilometers to Miles, divide by 1.609344. It may be easier to multiply is by 10, then chop it in half four times. Thus 70 kilometers becomes 700. Chopped in half it is 350, chopped again is 175, again is 87, and one more time is 43.5. Accurately it is 43.49.
