## Tips, information for using the Average Consumption and Miles Cost Calculator

### 1. How to calculate fuel efficiency (average consumption)?

The formula is relatively simple, divide the amount of gasoline consumed on a given road by the distance traveled and then multiply the result by 100. So if, for example, on a 430 miles road, the car consumed 5 gallons of gasoline, then the average fuel consumption (5/430) * 100 = 1.16 gal / 100 miles.

### 2. How do I calculate the cost per 1 mile of gasoline?

Once you have the fuel efficiency / average consumption, it is really very easy. Average consumption is the value of how many liters of gasoline a car travels per 100 km, so if you divide it by 100, you get how much the car consumes per miles. Just multiply that number by the price of 1 gallon of gasoline and you’ll get the result. Suppose the price of gas is 2.9 USD then the cost per miles is 0.03 USD / 1 mile.
