Km/L to L/100km Converter

Convert fuel efficiency from kilometers per liter (km/L) to liters per 100 kilometers (L/100km) instantly.

Enter Fuel Efficiency

km/L

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

  1. Enter your fuel efficiency in km/L in the input field.
  2. The result in L/100km is calculated automatically using the formula: L/100km = 100 / km/L.
  3. 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.
