I see this board has a lot of people from the U.S. where the standard of measurement is the Imperialistic system (miles, gallons, etc.) as well as some Europeans and Canadians where the Metric system (kilometers, liters, etc.) is the standard. A useful tool for bridging the Metric/Imperialistic systems so we can better understand each other is THIS WEB SITE. It has a lot of tools for converting from one system to the other. It will even convert fuel economy from one to the other, e.g. U.S.-MPG:Euro-Liter/100KM (30MPG=7.84 L/100KM). It might make it easier for some people when discussing things in one standard while trying to think in the other standard, especially for people like me who are bad a math.
