About Miles per Gallon (US) and Liters per 100 km

Miles per US gallon measures distance per fuel. Higher is better. It is the EPA window-sticker figure on every new car sold in the United States. 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. The two scales are related by the formula L/100km = 235.214583 / mpg. Miles per Gallon (US) is used in US car shopping and EPA ratings and in US road trip fuel planning. Liters per 100 km is used in European and Australian car specifications.

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).
