AI explanation
Formula
km/l = distance (km) ÷ fuel used (liters)Worked example
500 km on 40 liters
| Field | Value |
|---|---|
| Distance traveled | 500 |
| Distance unit | km |
| Fuel used | 40 |
| Fuel unit | liters |
| Kilometers per liter | 12.5 |
| Liters per 100 km | 8 |
| Miles per gallon | 29.4 |
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.
