Fuel Efficiency (Volume) Converter
Fuel efficiency by volume expresses how far a vehicle travels on a given volume of fuel, or how much it uses over a set distance. It offers a broader set of units than the Fuel Consumption converter, including kilometres per US gallon and litres per 100 miles.
1 Kilometer/Liter = 2.352145833 Mile/Gallon (US)
How to convert Kilometer/Liter to Mile/Gallon (US)
One Kilometer/Liter equals 2.352145833 Mile/Gallon (US), so multiply any value in km/L by 2.352145833 to get mpg. To convert back, divide by 2.352145833 — or multiply by 0.4251437074.
mpg = km/L × 2.352145833
Example: 25 km/L × 2.352145833 = 58.80364583 mpg.
Watch out: Distance-per-volume and volume-per-distance units are reciprocals, so higher is better for one and lower is better for the other.
