km/L
—
L/100km
Formula: L/100km = 100 ÷ km/L
The two units are inversely related — a higher km/L means a lower L/100km.

Summary
Convert fuel efficiency from kilometers per liter (km/L) to liters per 100 kilometers (L/100km) instantly.
How it works
- Enter your fuel efficiency in km/L in the input field.
- The result in L/100km is calculated automatically using the formula: L/100km = 100 / km/L.
- The reference table below shows common km/L values and their L/100km equivalents.
Use cases
- Convert a Japanese or Asian market fuel efficiency rating to the European L/100km standard.
- Compare vehicles whose specs are listed in different units.
- Estimate fuel costs when traveling in a country that uses L/100km.
- Understand how engine tuning or driving habits affect consumption in both units.
