FAQ

Why is the km/L to L/100km conversion a division?

km/L measures distance per fuel unit (higher is better), while L/100km measures fuel per distance (lower is better). They are reciprocals scaled by 100: L/100km = 100 ÷ km/L.

How do I quickly estimate L/100km from km/L?

Divide 100 by the km/L value. A car getting 15 km/L uses 100 ÷ 15 = 6.67 L/100km.

Which metric is more common globally?

L/100km is standard in Europe, Australia, and Canada. km/L is common in Japan, India, and parts of South America. Both are metric system units.

Is 20 km/L fuel efficient?

20 km/L equals 5 L/100km, which is very efficient for a gasoline car. This is typical of small hybrids and diesel compacts.

How do you convert kilometers per liter to liters per 100km?

Divide 100 by the kilometers per liter value. Formula: L/100km = 100 ÷ km/L. For example, 20 km/L = 5 L/100km.

How do you convert liters per 100km back to kilometers per liter?

The same operation works in both directions: km/L = 100 ÷ L/100km. For example, 5 L/100km = 20 km/L.

Why do kilometers per liter and liters per 100km move in opposite directions?

They are inverse measures of the same quantity — their product is always 100. A higher km/L value therefore always means a lower L/100km value, and doubling one halves the other.
