Speaking of Imperial gallons, I only recently found out that car advertisements in Canada show MPG (Imp.) numbers which look "better" than MPG (US), followed by the L/100km figure in small prints. If you don't know this, and because 99% of the time you talk MPG in Canada it's in US gallons, I think it's borderline misinformation. The rest of Europe also uses L/100km, but to me km/L makes more sense so I can quickly figure out how far I can get once the fuel reserve light comes on with 10L left or something.

As said you are wrong about Canada using US gallons, we have (did) always used Imperial gallons and any Canadian MPG claims would have been in Imperial. The car manufactures would have been in deep poop as we have strict measurement laws. Oil manufactured/packaged in Canada will be in full liters, but if it's packaged in the US it by law must be labeled in metric and French. So a "liter" of US specialty oil that is really a US quart will be measured as .946 liters.
As far as conversion of MPG to L/100km this is a prime example of how you must totally forget Standard and think in Metric.
Does anyone remember the Clint Eastwood movie Firefox? The flashback scene to fire weapons he was told "You must think in Russian". Same thing "you must think in Metric".
Say your car gets 10L/100km (10 liters per 100 kilometers), just move the decimal place so 10L/100km = 1
.0L/10
.0km or 10/100km = 100L/1000km
Within seconds you know simply doing the math in your head you need 1 liter to go 10KM or 100L to go 1000km.
When you think in metric things become quite simple, because most of the time when calculating you are just moving the decimal place.
