About these units
Kilometer per Liter
Kilometers per liter is used as the primary fuel economy standard in Japan, India, South Korea, and Latin America. Like mpg, it is a distance-per-volume metric where higher values indicate better economy.
Miles per Gallon (US)
US mpg is defined by the EPA testing procedure and appears on all new vehicle window stickers in the US. Its basis in gallons and miles makes it incompatible with metric measures without a conversion factor.
