Calculate fuel efficiency (km/L or kmpl) from distance and fuel used. Compare car mileage.
| Mileage (km/L) | — |
| Mileage (L/100km) | — |
| Mileage (US mpg) | — |
| Cost per km | — |
Mileage = distance ÷ fuel used. L/100 km = 100 ÷ km/L. Miles per US gallon = km/L × 2.35215. Cost per km = fuel price ÷ km/L. For a fair figure, fill the tank fully both times and use the distance between the two fill-ups.
