Liters per 100 km to Kilometers per Liter (L/100 km to km/L)
Liters per 100 km and kilometers per liter are inversely related: km/L = 100 ÷ L/100 km, so 15 L/100 km = 6.666666667 km/L.

How to Convert Liter per 100 km to Kilometer per Liter
- km/L = 100 ÷ L/100 km
- L/100 km = 100 ÷ km/L
- Example: convert 15 L/100 km to km/L: 100 ÷ 15 = 6.666666667 km/L
Formula
km/L = 100 ÷ L/100 km
Derivation from SI units:
- Fuel used in litres per 100 km; km/L = 100 ÷ (L/100 km), so the scales are reciprocal.
- Distance in kilometres travelled on one litre of fuel.
- Solving for km/L: km/L = 100 ÷ L/100 km (a higher L/100 km means a lower km/L)
Both units are defined exactly, so the factor is exact. Liter per 100 km definition: liter per 100 kilometers; Kilometer per Liter definition: kilometer per liter.
Worked examples
- A reading of 6 L/100 km converts to 16.66666667 km/L.
100 ÷ 6 = 16.66666667 km/L - A value of 9 L/100 km is 11.11111111 km/L.
100 ÷ 9 = 11.11111111 km/L

Where it's used
Liters per 100 km are used for official fuel consumption ratings in Canada, Australia and Europe, while kilometers per liter appear in car mileage in India (kmpl), Japan and Brazil. Both measure fuel economy (distance per volume of fuel), but one system is the inverse of the other, so a fixed constant is divided by the value.

Frequently asked questions
What is the formula for liters per 100 kilometers to kilometers per liter?
km/L = 100 ÷ L/100 km. The two systems are inversely related, so divide the constant by the value; do not multiply. For example, 100 ÷ 15 = 6.666666667 km/L.
Why does a higher L/100 km give a lower km/L?
Liters per 100 km counts length per unit mass (an indirect system), while kilometers per liter counts mass per unit length (a direct system). A finer yarn has a higher indirect number and a lower direct number.
Is the L/100 km to km/L conversion exact?
Yes. Both units are defined exactly, and 1 L/100 km is exactly 100 km/L.
