This tool will help you quickly convert fuel efficiency values between miles per gallon (mpg), kilometres per litre (km/L), litres per 100 kilometres (L/100 km), and litres per mil.
Enter the initial value in the From field, select corresponding "From" and "To" units, and then click Convert.
Fuel consumption is the amount of fuel used per unit distance. The measurement units used to express vehicle's fuel consumption include: litres per 100 kilometres (L/100 km), gallons per 100 mi (gal/100 mi), and litres per mil. In the case of the fuel consumption units, the lower the value, the more economic a vehicle is.
The mil unit used here stands for the Scandinavian mile which is defined as 10 kilometres.
Fuel economy is the distance traveled per unit volume of fuel used. The following units are typically used to describe vehicle's fuel economy: kilometres per litre (km/L) and miles per gallon (mpg or mi/gal). In this case, the higher the value, the more economic a vehicle is.
Efficiency of electric vehicles (EVs) is commonly expressed using different units - kilowatt hours per 100 miles (kWh/100 mi) or kilowatt hours per 100 kilometres (kWh/100 km). To compare EVs and internal combustion engine vehicles, use our MPGe Converter.
To convert between L/100 km and mpg US, use the following formulas: mpg US = 235.21 ÷ L/100 km L/100 km = 235.21 ÷ mpg US
Note: 1 US gallon = 3.785 L
To convert between L/100 km and mpg Imp, use the following formulas: mpg Imp = 282.48 ÷ L/100 km L/100 km = 282.48 ÷ mpg Imp
Note: 1 imperial gallon = 1.2 US gallons = 4.546 L
