What is Fuel Economy?
Fuel economy tells you how far your car can go with a certain amount of fuel. It helps you understand how much gas your car uses. Different countries use different ways to measure fuel economy.
In the United States, we use MPG (miles per gallon). This means how many miles you can drive with one gallon of gas. In many other countries, they use km/L (kilometers per liter) or L/100km (liters per 100 kilometers).
Our fuel economy converter helps you change between these different measurements. This is useful when you buy a car from another country or travel to different places.
