Fuel Mileage Calculator
Calculate your vehicle's fuel efficiency (e.g., MPG or km/L).
About this Tool
The Mileage Calculator helps you determine your vehicle's fuel efficiency, commonly expressed as miles per gallon (MPG) or kilometers per liter (km/L). By tracking your mileage, you can monitor your vehicle's performance, estimate fuel costs, and identify potential maintenance issues.
Common Use Cases
Tracking Fuel Economy
Monitor your car's performance over time to see if its fuel efficiency is changing.
Estimating Trip Costs
Use your mileage to get a more accurate estimate of how much fuel you'll need for a road trip.
Identifying Maintenance Issues
A sudden drop in mileage can be an early indicator of a problem with your vehicle, such as low tire pressure or an engine issue.
Pro Tips
- !
Be Consistent
For the most accurate calculation, fill your tank completely, reset your trip odometer, and then drive until the tank is nearly empty before filling it up again. Use the distance from your trip odometer and the amount of fuel you just added.
- !
Units Matter
Make sure your distance and fuel units match. If you measure distance in miles, use gallons for fuel to get MPG. If you use kilometers, use liters to get km/L.
- !
Driving Habits
Your driving style significantly impacts mileage. Aggressive driving (fast acceleration and hard braking) can lower your fuel efficiency by up to 30%.
