Frequently Asked Questions
Fuel efficiency (MPG) is calculated by dividing the distance traveled (in miles) by the fuel used (in gallons). Our calculator does this automatically.
You need the distance traveled in miles, the amount of fuel used in gallons, and the price per gallon of fuel.
Currently, this calculator uses miles and gallons. For metric conversions, you may need to convert units first.
