Mileage Calculator

Calculate your vehicle's fuel efficiency (km/l, mpg, and liters/100km) from distance traveled and fuel used.

  • Free to use
  • Accurate results
  • No registration required
  • Works on all devices
Enter your distance traveled and fuel used to calculate your vehicle's mileage in km/l, liters/100km, and mpg.

Your result

12.5 km/l

AI explanation

Formula

km/l = distance (km) ÷ fuel used (liters)

Assumptions

  • Uses the odometer-reading and fuel-fill method — enter the distance covered by the fuel amount you entered, not your vehicle's lifetime total.
  • Converts between units using 1 mile = 1.609344 km and 1 US gallon = 3.785411784 liters.

Frequently asked questions

How do I measure fuel used accurately?

Fill your tank completely, reset your trip odometer (or note the reading), drive normally, then fill up again completely — the liters needed to refill is your fuel used, and the trip odometer reading is your distance traveled.

What is a good km/l figure?

It varies widely by vehicle type — small hatchbacks often achieve 15-20+ km/l, mid-size sedans 12-16 km/l, and SUVs 8-14 km/l, with driving style and traffic conditions affecting real-world figures significantly.

Why does my mileage vary between fill-ups?

Driving conditions (city vs. highway), traffic, AC usage, tire pressure, and load all affect real-world fuel efficiency — a single reading is a snapshot, not a guarantee.
