Tips for converting liters per 100 km to miles per US gallon

Lower L/100 km is better, the opposite of mpg. Divide roughly 235 by the L/100 km figure to get US mpg.
The relationship is not linear, so halving L/100 km doubles mpg rather than adding a fixed amount.
European test cycles and US EPA tests differ, so even a perfect unit conversion may not match the EPA sticker for the same car.
