Fuel Economy Converter
Convert between MPG, L/100km, and km/L.
How It Works
MPG (US) and MPG (UK) differ because gallons differ. L/100km is the standard in most of the world; lower is better. km/L is common in Asia.
FAQ
US vs UK MPG?
1 UK gallon = 1.201 US gallons, so UK MPG numbers are higher than US for the same car.
Why L/100km?
