Result updates as you type.
Type the figure you have.
L/100km, US MPG, UK (imperial) MPG or km/L.
Every other unit is shown instantly — US and UK gallons differ, so the two MPG figures are not the same.
L/100km = 235.215 ÷ US MPG (or 282.481 ÷ UK MPG). They are inversely related, so a higher MPG means a lower L/100km.
The imperial (UK) gallon is about 20% larger than the US gallon, so the same car shows a higher number in UK MPG than US MPG.
Kilometres per litre, used in some markets. km/L = 100 ÷ L/100km.
