Enter a number in the From field, select units, and then click Convert.
This tool will help you quickly convert electric vehicle (EV) energy consumption expressed in kilowatt hours per 100 miles (kWh/100 mi) or kilowatt hours per 100 kilometres (kWh/100 km) into miles per gallon gasoline equivalent (mpge) or gasoline litres equivalent per 100 kilometres (Le/100 km).
Enter the value you wish to convert in the From field, select the initial and target units, and then click Convert.
For your convenience this tool will also convert the entered value into other often used fuel efficiency units.
Traditionally, the fuel efficiency of internal combustion engine (ICE) vehicles has been evaluated using miles per gallon (MPG or mpg or mi/gal) in the United States and liters per 100 kilometers (L/100 km) in most other countries. The mpg unit represents the distance a vehicle can travel per unit volume of fuel consumed. It indicates how many miles a vehicle can cover on a gallon of fuel. In contrast, the L/100 km unit expresses the amount of fuel consumed per unit distance traveled. It indicates how many liters of fuel are needed to travel 100 kilometers. A higher mpg value or lower L/100 km value signifies greater fuel efficiency.
Different units of measurement are required for efficiency assessment of electric vehicles (EVs). Kilowatt hours per 100 miles (kWh/100 mi) or kilowatt hours per 100 kilometres (kWh/100 km) is commonly used to express the amount of electrical energy consumed per unit distance. A lower kWh/100 mi or kWh/100 km value signifies better energy efficiency.
In the United States, the Environmental Protection Agency (EPA) provides the miles per gallon (mpg) rating for ICE vehicles and the miles per gallon equivalent (mpge or MPGe) rating for electric or alternative fuel vehicles. MPGe represents the number of miles an electric vehicle can travel on the same amount of energy as contained in one gallon of gasoline. To help consumers compare different vehicle types and models, a Fuel Economy Label, commonly known as the Monroney sticker, is displayed on all new cars for sale. The label indicates the vehicle's fuel economy information for different driving conditions, annual fuel cost, and greenhouse gas ratings, etc.
In Canada, an EnerGuide label is required to be displayed on all new vehicles for sale. The fuel consumption ratings provided on the label are based on standardized testing procedures conducted by Natural Resources Canada. The EnerGuide label includes the following key details: fuel consumption ratings in litres per 100 kilometres (L/100 km) or gasoline litres equivalent per 100 kilometres (Le/100 km) for EVs, estimated annual fuel cost, greenhouse gas emissions and comparison data. For ICE vehicles, the label also provides fuel economy ratings in miles per imperial gallon (mpg imp).
In Australia, all new vehicles must display a Fuel Consumption Label on the front windscreen. For ICE vehicles, the label indicates the vehicle's fuel consumption in litres per 100 kilometres (L/100 km) and carbon dioxide (CO2) emissions in grams per kilometre (g/km). For pure electric and plug-in hybrid electric vehicles, the label also provides the energy consumption in watt hours per kilometer (Wh/km) and expected range when fully charged.
The European Union energy label is mandatory for new passenger cars and light commercial vehicles sold within the EU. The label provides the vehicle's fuel consumption in liters per 100 kilometers (L/100 km) or kilometers per liter (km/L), CO2 emissions in grams per kilometer traveled (g/km), and assigns an energy efficiency class ranging from A (most efficient) to G (least efficient).
In the UK, car dealers are required to display an Environmental Label on every new car for sale. The label shows the fuel consumption and CO2 emissions. Fuel consumption figures are expressed both in litres per 100 kilometres (L/100 km) and in miles per imperial gallon (mpg imp). Electricity consumption is shown in miles per kilowatt hour (mi/kWh).
To compare the efficiency of different vehicle types, such as internal combustion engine and electric vehicles, a common approach is to convert the energy efficiency measures into miles per gallon gasoline equivalent.
To convert kilowatt hours per 100 miles (kWh/100 mi) into miles per US gallon equivalent (MPGe) the following formula can be used: MPGe = 3370.5 ÷ E
where
To convert electrical energy consumption value, expressed in kilowatt hours per 100 kilometres (kWh/100 km), into gasoline litres equivalent per 100 kilometres (Le/100 km) the following formula can be used: Le/100 km = E ÷ 8.9039
where
By converting kWh/100 miles into MPG equivalent and comparing the MPG values, it is possible to directly compare fuel efficiency of different vehicle types. However, keep in mind that these metrics provide a simplified view, and other factors, such as driving conditions, vehicle weight, aerodynamics, and driving style, can also influence overall efficiency.
