How to Calculate Gas Mileage
Before using the fuel mileage calculator, you will first need to log the data you will need to enter into the calculator (or that you will need to calculate MPG) as detailed below:
- The next time you visit the gas station to refill your car's gas tank (the less fuel you have in your tank, the better), write down the odometer reading (beginning reading).
- On your return trip to the gas station to refill your car's gas tank, write down the odometer reading (ending reading) and the number of gallons or liters it took to refill the tank.
If you want to calculate the fuel economy yourself, here is the formula:
ending odometer reading
- beginning odometer reading
÷ number of gallons or liters to refill tank
Of course, now that you have discovered this page you don't need to know how to calculate gas mileage. All you need to do is plug in the numbers and click the "Calculate Fuel Economy" button.
How to Calculate Price of Fuel
If you know the number of units pumped and the total price of the fill, this mini calculator will tell you the price per unit of fuel.
The Price of Gas is NOT the Reason for High Gas Expenses
I always have to chuckle when I overhear someone complaining about the price of gas, especially when they are:
- leaning over the hood of their idling SUV that has a low tire on the right front ...
- having just stopped by the coffee shop for a $3, 12-ounce cup of designer coffee ...
- while on their way home from fighting stop-and-go rush hour traffic ...
- and are now parked in an out-of-the-way grocery store to pick up a loaf of bread.
First off, why aren't they complaining about the $32-per-gallon cup of designer coffee they are holding in their hands?!
Secondly, if they are so concerned about the cost of gasoline, why are they driving a gas guzzling SUV?
Thirdly, why didn't they buy more bread the last time they made a special trip to the grocery store?
Why don't they take a minute to air up that low tire?
And finally, why have they chosen to work at a job that forces them to drive during the most fuel-sucking time of the day?
My point is, the price of gasoline is only a tiny part of the gasoline expense equation. More important factors include:
- The MPG rating of the vehicle you drive.
- The conditions under which you drive your vehicle.
- The planning needed to avoid unnecessary trips.
- And having the freedom to choose when to commute and how (walk, bike, carpool, or public transportation).
