MPG to L/100 km

Convert fuel economy between MPG and liters per 100 km.

About MPG to L/100 km

The two units are inverse measures, linked by the 235.215 constant for US gallons. A low L/100 km figure equals a high MPG figure and vice versa. Europe and North America quote economy in opposite directions, so a quick conversion prevents misjudging how efficient a vehicle really is.
