I now live in France and have done for about three years. I still though think of fuel consumption in mpg. Trouble is, all I can get is the rather unwieldy l/100km. I've tried all the conversion factor websites that I can find but I can't find a formula that converts one to the other. Have I missed it or isn't there a straightforward formula?
