How can you calculate your car's fuel efficiency?

I believe that some time ago you published to way to work out your car's fuel efficiency (in litres/100km and also how to convert to miles per gallon). I have made a note of this and use the calculation regularly, however I have just searched your website for this information in order to send it to a friend, but I can't find it.
