Kilometers per Liter to Liters per 100 km Converter

Convert fuel efficiency from km/L to L/100km with this free calculator.

What this tool does

Convert fuel efficiency from km/L to L/100km with this free calculator. Type an amount in kilometers per liter, choose the units, and the tool converts it to liters per 100 kilometers. It converts between these two fuel economy units, in either direction.

Inputs

  • Value: A number.
  • From: Choose one: Kilometer per liter, Liter per 100 kilometers. Starts as Kilometer per liter.
  • To: Choose one of the same 2 units as "From". Starts as Liter per 100 kilometers.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount. It appears once every required field has a valid value.

Worked examples

Conversions from kilometers per liter to liters per 100 kilometers:

  • 1 km/L = 100 L/100 km
  • 5 km/L = 20 L/100 km
  • 10 km/L = 10 L/100 km
  • 50 km/L = 2 L/100 km
  • 100 km/L = 1 L/100 km

Divide 100 by the number of kilometers per liter to get liters per 100 kilometers. Both units are exact definitions, so 100 is the exact factor: 1 km/L = 100 L/100 km.

Sources: Kilometer per liter: exact by definition. Liter per 100 kilometers: exact by definition.

Limitations

  • Converts the unit of a fuel economy figure only. It does not work out fuel cost, trip fuel or a car's real-world economy.
  • Offers kilometers per liter and liters per 100 km only. Miles per gallon is not on this page.
  • Zero and negative values are refused, because zero distance per unit of fuel has no finite L/100 km figure.

FAQs

Q: How do I convert km/L to L/100 km?
A: Divide 100 by the km/L figure. 10 km/L is 10 L/100 km, and 20 km/L is 5 L/100 km.
Q: Why does a higher km/L mean a lower L/100 km?
A: The two are reciprocals. Kilometers per liter measures distance per unit of fuel, so a higher number means less fuel used. Liters per 100 km measures fuel per distance, so a lower number means less fuel used.
