# Gas Calculator

If you want to estimate how much gas you will use on your next road trip, this **gas calculator** is for you. In this calculator, you will learn:

- The importance of
**understanding fuel economy**; **How to calculate how much gas it will take to run any certain distance**;**How to estimate the cost of gas for any trip**; and**How to use this gas calculator**.

## Understanding fuel economy

**Fuel economy** is a measure that we can use to **estimate the efficiency** of our vehicles. Its value varies from one vehicle to another and may change depending on the type of road you drive on, your driving velocity, and how much weight a car carries. We usually express fuel economy in terms of **how far a vehicle can go per volume of gas or fuel**.

Another metric related to fuel economy is **fuel consumption** which we express in terms of **the amount of gas or fuel a vehicle needs to run a certain distance** (e.g., liters per kilometer or liters per 100 kilometers). In an ideal situation, we want a low fuel consumption vehicle.

Knowing our vehicle's fuel economy or fuel consumption can help us **plan our trips** and **budget our fuel expenses**. In the next section of this text, let us learn how to use this gas calculator to utilize fuel economy for our gas cost calculations.

## How to use this gas calculator

Here are the steps you can follow when using our gas estimation calculator:

**Choose**your**trip type**.**Select**your**car**model from the options. If your car is not there,**select**`Other vehicle`

and**enter**your vehicle's**fuel economy**. You can check out our MPG Calculator to learn how to determine your car's fuel consumption or fuel economy if you do not know it yet.**Enter**the**distance**you are traveling. By this time, our tool will display a gas estimation you will use for that trip.**Input**the**fuel price**in your area to find the**cost of the trip**you are having.- You can also
**enter**the**number of people**splitting the bill to divide the fuel cost evenly.

## How to calculate how much gas it will take to run any certain distance

To calculate how much gas you will use in any length of trip:

**Know your car's fuel consumption.**Let's say your car only uses`8.5 liters of gas to travel a distance of 100 km`

.**Determine how far your next trip will be.**Google Maps can help you with that, but you can use any other maps or source of this information for this step. Say you need to travel from the Empire State Building to The White House, which is around`374 km`

away.**Substitute those values into this equation**:

- Finally, to calculate the cost of gas for trips like this, multiply the fuel price (say $ 1.20) by the volume of fuel used.

If you can't find your car or the fuel consumption is different, select "Other vehicle" option instead.
