Formula
Converts via km/l as a common intermediate; l/100km is handled as a reciprocal (100 ÷ km/l)Worked example
6.5 l/100km to km/l
| Field | Value |
|---|---|
| Amount | 6.5 |
| From unit | l100km |
| To unit | kmpl |
| Converted value | 15.3846 |
Assumptions
- l/100km is the standard fuel consumption unit across most of Europe — lower is more efficient, the opposite direction from km/l and mpg.
- US mpg uses the US gallon (3.785411784 liters); UK/imperial mpg uses the larger imperial gallon (4.54609 liters).
Frequently asked questions
What does a lower l/100km number mean?
It means better fuel efficiency — you're consuming less fuel to travel the same 100km distance. This is the opposite direction from km/l and mpg, where a higher number is better.
How is this different from the Fuel Economy Converter?
Same underlying conversion — this page defaults to converting FROM l/100km (the "consumption" framing common in Europe), while the Fuel Economy Converter defaults to converting FROM km/l.
How do I compare a European car's spec sheet to an Indian one?
European spec sheets typically quote l/100km, while Indian (ARAI) spec sheets quote km/l — use this converter to compare the two directly.
