It should be noticed that in
Europe (
metric Europe at least), we do not count in km/l , but in l/100 km, which takes an extra
division (by the number op mpg's)/
multiplication (*100) step for
conversion.
Therefore one
mpg equals 236 l/100km, and a
consumption of 50 mpg gives 236/50 l/100km, or 4,72 l/100km
