About Kilometers per Liter and Miles per Gallon (US)

Kilometers per liter measures distance per unit fuel in metric terms — higher is better. Japan, India, and much of Asia and Latin America quote car economy in km/L. 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. The two units are related by a formula rather than a fixed factor; a value of 1 Kilometers per Liter corresponds to 2.35214583 Miles per Gallon (US). Kilometers per Liter to Miles per Gallon (US) conversion comes up most often in car economy in Japan, India, and Asia and in motorcycle fuel efficiency, typically when figures need restating for US car shopping and EPA ratings.

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).
