This converts European mileage. However, the tool below does not do the proper conversion. European mileage is not measured in kilometers per litre, but in litres per 100 kilometers, and US mileage is measured in miles per gallon. You can see that the gasoline value is in the numerator (top) for Eurpean mileage and in the denominator (bottom) for US mileage. However, this tool should give you a figure that you'll be able to understand when travelling in Europe or when figuring out your gasoline budget for your trip.
