Calculate your vehicle's fuel efficiency in miles per gallon (MPG) by entering distance traveled and fuel consumed.
Learn how to use the Fuel Efficiency Calculator and understand its working principles.
Fuel efficiency is a measure of how far a vehicle can travel while consuming a certain amount of fuel. It is commonly expressed in miles per gallon (MPG) in the United States.
A higher MPG value indicates better fuel efficiency, meaning the vehicle consumes less fuel to travel a given distance. The average fuel efficiency of a car in the US is around 25-30 MPG.
For example, if you traveled 300 miles and consumed 10 gallons of fuel, your fuel efficiency would be:
MPG = 300 miles / 10 gallons = 30 MPG
