That is an annoying construct.  I'd rather see it multiplied by 10 and be given 
as L/1000 km, which could also be written as L/Mm, not that megameter is much 
used, but it should be.   So a typical car would be 100 L/Mm.  1000 km might be 
a little light here, but I am assuming it is about a typical monthly driving 
distance in Europe.

Dear John,


You're right. Once again I became confused by that stupid unit construction 
L/100 km!
