About Fuel Economy Conversions

Fuel economy is the relationship between the distance traveled and the amount of fuel consumed by a vehicle. It is a measure of how efficiently a vehicle uses fuel.

Common units include miles per gallon (mpg), kilometers per liter (km/L), and liters per 100 kilometers (L/100km). The first two express how far a vehicle can travel per unit of fuel,
while the last expresses how much fuel is needed to travel a fixed distance.

Fuel economy conversion is essential in the automotive industry, transportation planning, and environmental assessment. Different regions use different units:
miles per gallon in the United States and the United Kingdom, kilometers per liter in Japan and some other countries, and liters per 100 kilometers in most European countries.

Accurate fuel economy conversion is crucial for comparing vehicles across different markets and for consumers traveling between regions with different measurement systems.

Fuel Economy Units Explained

Miles per Gallon (mpg)

Miles per gallon is a unit of fuel economy that expresses the distance traveled in miles per one US gallon of fuel consumed. It is commonly used in the United States and the United Kingdom.

Kilometers per Liter (km/L)

Kilometers per liter is a unit of fuel economy that expresses the distance traveled in kilometers per one liter of fuel consumed. It is commonly used in Japan and some other countries.

Liters per 100 Kilometers (L/100km)

Liters per 100 kilometers is a unit of fuel consumption that expresses the amount of fuel in liters required to travel 100 kilometers. It is commonly used in most European countries and is the inverse of fuel economy.

Miles per Liter (mi/L)

Miles per liter is a unit of fuel economy that expresses the distance traveled in miles per one liter of fuel consumed. It is sometimes used for comparing fuel economy between US and metric systems.

Gallons per 100 Miles (gal/100mi)

Gallons per 100 miles is a unit of fuel consumption that expresses the amount of fuel in US gallons required to travel 100 miles. It is the inverse of miles per gallon and is sometimes used for comparing vehicles with very different fuel economies.
