Gas Mileage Calculator
Calculate MPG or L/100km; track fill-ups, show average.
What is the Gas Mileage Calculator & How does it work?
The Gas Mileage Calculator helps users determine their vehicle’s fuel efficiency by inputting the distance traveled and the amount of fuel used. This tool not only calculates miles per gallon (MPG) or liters per 100 kilometers (L/100km) but also allows tracking multiple fill-ups to compute an average fuel efficiency over time. Comparing these results with EPA estimates can provide insights into how your vehicle’s performance aligns with industry standards.To calculate MPG, divide the total distance traveled by the total gallons of fuel used. For L/100km, multiply the MPG result by 235.2146 to convert it to liters per 100 kilometers. This conversion factor is derived from the relationship between miles and kilometers (1 mile = 1.60934 kilometers) and gallons and liters (1 gallon ≈ 3.78541 liters).
MPG = \frac{Distance}{Fuel\ Used}
MPG = Miles per Gallon, Distance = Total distance traveled in miles, Fuel Used = Total fuel used in gallons
