L/100km to MPG Converter

Convert litres per 100 kilometres into miles per gallon, with both US and UK imperial results shown together. This is the direction most European vehicle specifications need converting in order to compare against an American or British review — and the one where a rough mental conversion is most likely to be wrong.
Because L/100km and MPG move in opposite directions — lower is better on one scale, higher on the other — even getting the direction of the comparison right by eye is harder than it looks. Entering the exact figure here removes that guesswork entirely.
