About these units
The mile per imperial gallon (MPG (UK)) is an imperial unit of fuel economy, equal to 0.35400619 kilometers per liter.
The mile per us gallon (MPG (US)) is a US customary unit of fuel economy, equal to 0.42514371 kilometers per liter.
Going the other way, 1 mile per us gallon = 1.2009499 miles per imperial 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.
