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

Frequently Asked Questions
How do I calculate my car's miles per gallon?
Divide the total distance traveled by the amount of fuel used.
Can I use this calculator for liters per 100 kilometers?
Yes, you can switch to L/100km mode in the settings.
How do I track multiple fill-ups?
Enter each fill-up's details separately; the calculator will compute an average over time.
What does MPG stand for?
MPG stands for Miles Per Gallon, a measure of fuel efficiency.
Can I compare my results with EPA estimates?
Yes, the calculator allows you to input EPA estimates and compare them with your actual mileage.
Is this calculator compatible with metric units?
Yes, it supports both imperial (MPG) and metric (L/100km) units.
How accurate are the results provided by this calculator?
The accuracy depends on the precision of your inputs; regular updates can improve reliability.
