About the units
Miles per imperial gallon. Miles per imperial gallon rests on the imperial gallon of exactly 4.54609 litres, fixed by the Weights and Measures Act 1985. That gives the conversion factor 282.480936: 7 litres per 100 kilometres is 40.4 mpg. The measure lives on in British everyday speech and the British motoring press, and printed car advertising must still give the official consumption in mpg as well as in litres per 100 kilometres or kilometres per litre. Here is the worst trap of the category: a 30 mpg (US) car is 36.0 mpg (UK).
Litres per 100 km. Litres per 100 kilometres is the EU’s compulsory measure of fuel consumption. The car labelling directive requires the official figure to be given in litres per 100 kilometres to one decimal place, on a label of A4 size. The measure is built from two legal units and is therefore legal itself. Lower is better here, the opposite of miles per gallon. And the scale is not linear: going from 12 to 10 litres per 100 kilometres saves more fuel than going from 7 to 5.
