About Liters per 100 km and Miles per Gallon (Imperial)
Liters per 100 kilometers measures fuel consumption. Lower is better. It is the official fuel economy figure in Europe, Australia, and most metric countries, and inverts the efficiency units used elsewhere. Miles per imperial gallon uses the larger UK gallon (4.54609 L), so the same car scores about 20% higher than in US mpg. UK car reviews and older Commonwealth figures use it. The two scales are related by the formula mpg imp = 282.480936 / L/100km. Liters per 100 km is used in European and Australian car specifications and in fleet fuel budgeting. Miles per Gallon (Imperial) is used in UK car reviews and adverts.
Precision and Rounding:Fuel economy units are reciprocal of each other: consumption (L/100 km) falls as efficiency (mpg, km/L) rises, so conversions are formula-based, not simple factors, and small mpg differences matter more at low values than high ones. One decimal place is standard for window stickers and trip computers.
Fuel-economy results use exact volume and distance definitions with the reciprocal formulas shown on each page (reference).
