# MPG Calculator

This MPG calculator (a.k.a a miles per gallon calculator) is a useful tool that allows you to calculate your fuel consumption. When you plan a trip, you'll probably want to know how much it will cost before you set off. That is not the only use of this MPG calculator; maybe you're curious about your gas mileage over a particular distance. If you are interested in either of these topics, then you no longer need to fret about calculations, this fuel efficiency calculator will estimate it for you instantaneously!

## What is gas mileage?

Gas mileage is the relationship between the distance you've traveled and the amount of fuel you have burnt. Your gas consumption depends on a range of factors. This include your car model, the year of production, the engine size and the efficiency of your driving. For example, the average gas mileage of Ford Focus 1.6 produced between 1998 and 2005 amounts to 7.61/100 km. 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 fuel efficiency - you may need to worry about what the cost is of exceeding your lease mileage!

You can calculate the fuel efficiency with the following formula (imperial):

`MPG = distance (miles) / average gas consumption (gallons)`

In the metric system, the formula is:

`MPG = distance (km) x average gas consumption (litres) / 100 km`

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 covered and the average fuel consumption of your car.

All you need to do is input:

- distance - how far you plan to travel
- fuel economy - the average fuel use of your car

In the advanced mode you can also enter:

- the price of petrol

Then the MPG calculator will estimate the total 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 for it.

If you don't know the average fuel use of your car in liters, just click on the unit to change it. You can also 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

As you can see, the MPG calculator is a very useful for everyone who wants to plan a car trip. This application may save both time and money.
