km/L to L/100 km formula
Kilometers per liter and liters per 100 kilometers are reciprocals of each other, so one formula works in both directions:
km/L = 100 ÷ L/100 km
km/L to L/100 km conversion table

When to use each unit
km/L answers "how far can I go on one liter?" and is common in Turkey, Japan, India, and Latin America. L/100 km answers "how much fuel do I need for 100 km?" and is the standard in Europe. Because L/100 km grows in a straight line with fuel use, it is easier for comparing running costs: going from 10 to 8 L/100 km saves exactly 2 liters every 100 km.
Frequently asked questions
How do I convert km/L to L/100 km?
Divide 100 by the km/L value. For example, 15 km/L is 100 ÷ 15 = 6.67 L/100 km.
How do I convert L/100 km to km/L?
It works the same way: divide 100 by the L/100 km value. 5 L/100 km is 100 ÷ 5 = 20 km/L.
Which is better, km/L or L/100 km?
Neither is more accurate; they show the same information. L/100 km makes fuel costs easier to compare because it grows in proportion to the fuel used, while km/L feels more intuitive to many drivers. With km/L higher is better, with L/100 km lower is better.
Which unit does Fuellow use?
The Fuellow app can show your consumption in L/100 km or km/L — switch between them to read your numbers your way.
