Canadians typically express in litres/100km.
South Africans typically express in litres/100km too, but also in 
km/litre sometimes (at least it was done 10 years or so ago).

Just by the way, in most 'metric' places it is litre, not liter, and the 
SI unit is litre as well. You may want to get that right if you are 
planning to support international markets... ;-)
