In order to calculate accurately, the average miles per gallon rating of the vehicle must be known. After filling up the fuel tank and calculating the total distance traveled, the following formula will be used for calculation:

Gallons consumed x 100 / miles covered = gallons per 100 miles

For example, if a vehicle uses 1 gallon of gas to travel 22 miles, its fuel consumption per 100 miles will be 1 x 100 / 22 = 4.54.
