## What is gas mileage?

Gas mileage is the relationship between the distance you've done and the amount of fuel which has been burnt. It's crucial to know the fuel consumption of your car. Otherwise, you will not be able to estimate how much petrol you need to cover a particular distance.

If you're leasing a car, there's more to worry about than just the fuel efficiency - make sure to check what will be the payment for exceeding lease mileage!

MPG = distance x average gas consumption / 100km

However, it's much easier to use the MPG calculator.

## How to use the fuel efficiency calculator?

The fuel efficiency calculator estimates gas mileage on the basis of the number of kilometers and the average fuel consumption of your car.

All you need to do is type:

- distance - the number of kilometers
- fuel economy - the average fuel use of your car

In the advanced mode also:

- the price of petrol

Then the MPG calculator will estimate the amount of fuel you will need for the whole route. The advanced version will determine the total cost of your tour as well.

If you want to share the cost between a few people, you may find our gas estimator useful. This tool automatically divides the total cost between the number of people who are going to pay it.

If you don't know the average fuel use of your car in liters but in another unit, you can easily convert it with our MPG converter. This tool operates with 3 different units:

- miles per US gallon
- miles per UK gallon
- liters per 100km
