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 units are related by a formula rather than a fixed factor; a value of 1 Miles per Gallon (US) corresponds to 235.214583 Liters per 100 km. Miles per Gallon (US) to Liters per 100 km conversion comes up most often in US car shopping and EPA ratings and in US road trip fuel planning, typically when figures need restating for 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.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
