How it works
MPG and km/L measure distance per fuel (higher is better), while L/100 km measures fuel per distance (lower is better), so they are inversely related: L/100 km = 235.215 ÷ MPG (US) and 282.481 ÷ MPG (UK). A UK (imperial) gallon is 20% larger than a US gallon, so the same car shows a higher MPG figure in the UK.
