Distance-per-volume seems intuitively comprehensible to people and they can usually do the simple arithmetic to answer the simple questions "how much range do I get from this fill?" or "how much petrol do I need to go this far?" If you told people their fuel consumption in "square metres" they'd look at you like you were some sort of nerd. (I like it otherwise, so I'm likely some sort of nerd also.)

:-) I am aware of this.

As it turns out, a more useful measurement would be square millimetres since this takes values of a reasonable size. Also, if you multiply by the amount of kilometres you travel you'll get the fuel consumption in litres, i.e. mm^2=L/km.
