About the units
Mile per US gallon (mpg)
Miles driven per US gallon, the fuel economy figure on US window stickers.
Kilometer per liter (km/L)
A unit of fuel economy.
Fuel economy is either distance per volume (mpg, km/L), where higher is better, or volume per distance (L/100 km), where lower is better. Converting between the two families is an inversion, not a multiplication. US and UK mpg differ because their gallons differ.
