What is a mile per gallon?
Miles per US gallon are the fuel economy unit of US window stickers and EPA ratings. Higher is better. Because it is a distance per volume, savings are not linear: going from 10 to 20 mpg saves far more fuel than going from 30 to 40 mpg.
What is a kilometer per liter?
Kilometers per liter tell how far a vehicle travels on one liter of fuel, like mpg with metric units. Japan, India and much of Latin America use it. Higher is better: 15 km/L is about 35 US mpg.
