Canada pretty much uses X litres/100km nowadays recently replacing mpg. The lower the litres, the more efficient the vehicle. It actually was fairly easy to become accustomed to these new metrics.
L/100km is roughly equivalent to L/h at highway speeds, and you can figure Litres to destination when you see a road sign by multiplying L/100km by the hundreds place.
With gas stations being upwards of a hundred kilometres apart in the prairies and northern ontario, especially at night, it's nice that this is so easy.
