What is mpg used in?

MPG, or miles per gallon, is a measurement used to evaluate the fuel efficiency of vehicles. It indicates how many miles a vehicle can travel on one gallon of fuel, helping consumers compare the efficiency of different cars. Higher MPG values generally suggest better fuel economy, which can lead to lower fuel costs and reduced environmental impact. MPG is commonly used in the automotive industry, by consumers when purchasing vehicles, and in regulatory discussions regarding emissions and fuel standards.
