When I figure my mileage (Being Canadian, sounds better than kilometerage ) I tend to think of Kilometers Per Liter, instead of Litres per 100km. I know that the L/100km conversion is new to this site (And I appreciate it) but was wondering if a toggle could be put in, or additional stats be displayed with that view? I just personally find it easier (And prefer) to think of the distance my car has traveled per liter, versus how many liters it'll take to push my car 100km. MPG=KM/L as far as keeping the numbers `meaning` the same. The math is just simple linear multiplication or division (Depending on how your DB is set to store its info) for US or UK gallons.
We did a bunch of research and asked people what stats they used to track their fuel economy, and then played with the data we had to create the stats you see.
I never recall a single person asking for a straight km/L calculation, as everyone either wanted mpg or the new standard L/100km, so we never included it.
If you're a bit of a programmer, you might want to check out greasemonkey and tweak out the stats output to what you need, but if not, if we get more feedback that people would like to see it, we'll consider adding it.
