The formula and examples

The conversion is a division: L/100 km = 235.21 ÷ mpg. So 20 mpg is 11.76 L/100 km, 30 mpg is 7.84 L/100 km and 40 mpg is 5.88 L/100 km.

The relationship is inverse: the more miles per gallon, the fewer liters per 100 km. Divide 235.2 by the mpg. The US gallon (3.785 L) is used. UK mpg use a larger imperial gallon and give different values: the tool shows them separately.

mpg, US × 235.21458 = l/100 km
l/100 km × 235.21458 = mpg, US
