Adjust Calculator Width % Adjust Calculator Width: Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view. Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".	Show/Hide Keypads Show/Hide Popup Keypads: Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.	Stick/Unstick Tools Stick/Unstick Tools: Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position. If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.

Gas expense factors other than the price of gas, and how to calculate MPG.

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).

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 manually 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 it took to refill the tank.

If you want to calculate MPG yourself, here is the formula:

MPG =
(
ending odometer reading
- beginning odometer reading
)
÷ number of gallons 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 Mileage" button.
