Fuel Consumption Conversion
Convert between MPG (US), MPG (UK), km/L and L/100km — the four ways the world measures how far a car goes on a litre of fuel.
Quick fuel economy converter
Pick any two units and convert immediately — no need to know which page to open first.
MPG without a qualifier means US gallons. Fuel economy is reciprocal, so a lower L/100km figure is the better one.
