The kilometer per liter (km/L) is a metric unit of fuel economy.
Going the other way, 1 kilometer per liter = 2.3521458 miles per us gallon. Fuel economy is the classic inverted conversion: more miles per gallon is better, but fewer litres per 100 km is better. Because the relationship is reciprocal, the graph is a curve, not a straight line. Note that a US gallon is smaller than an imperial gallon, so US MPG figures always look worse than UK ones for the same car.
