Convert a real fill up into a fuel consumption figure in liters per 100 kilometers, the standard economy measure across Europe, Australia, and most of the world. Enter the kilometers you drove and the liters of fuel you added at the pump, and this calculator returns your consumption plus the kilometers per liter and the US MPG equivalent. Lower liters per 100km means a more efficient trip, which is the opposite direction from MPG where higher is better, so it helps to see both. Tracking this number across several tanks reveals how traffic, terrain, air conditioning, and driving style affect your real economy. It is also handy for comparing a rental or a car you are thinking of buying. All calculations run in your browser with nothing sent to a server.
