Well, if you insist on expressing it 'the wrong way', a factor of 1000 should be used, as that is the default factor in the metric system. So that should be 440L/1000km, or 440L/Mm. (Which also solves the problem that L/100km is normally expressed in 2 digits, while km/L is expressed in 3.)

BTW, I read that article, where was stated that fuel consumption should be measured in g/100m. And I read grams per 100 meters first.
