Convert L/100km, km/L, mpg (US), and mpg (UK) for vehicle specs, international driving notes, automotive reviews, and trip records. Fuel-efficiency units can be confusing: lower L/100km usually means better efficiency, while higher MPG or km/L usually means better efficiency. US gallons and UK gallons are different, so confirm the source standard before comparing vehicles or articles. This tool converts units only; it does not calculate fuel cost, route expense, driving style, load, weather, maintenance condition, or real-world consumption.
