Questions
How many litres per 100 km are in a kilometre per litre?
One kilometre per litre is 100 litres per 100 km.
What is 5 kilometres per litre in litres per 100 km?
5 kilometres per litre is 20 litres per 100 km. The working is 5 km/L → 20 L/100 km.
Why can't I convert mpg with a simple multiplier?
Because the two measures run in opposite directions. Miles per gallon counts distance per unit of fuel; litres per 100 km counts fuel per unit of distance. One is the reciprocal of the other, so you divide rather than multiply.
Why is UK mpg always a bigger number than US mpg?
The Imperial gallon is about 20% larger, so the same car travels further on one of them. A car rated 30 mpg in the US is around 36 mpg in the UK, with nothing about the car having changed.
Going from 15 to 20 mpg, or 30 to 40 mpg — which saves more fuel?
The first, by a wide margin. Over 10,000 miles the 15-to-20 change saves about 167 gallons; the 30-to-40 change saves about 83. This is exactly the trap the inverse relationship sets, and why litres per 100 km is the easier measure to reason with.
