A random dimensional analysis that I find amusing about fuel consumption units:
liters / 100 km => m^3 / m => m^2
(volume) / (distance) => (area)
This can be interpreted as the cross-sectional area of a hypothetical trough of fuel running alongside the road, whose contents you slurp up and consume in your engine as you pass (in lieu of using fuel stored in an onboard reservoir).
