Global Fuel Calculatorkm/L to L/100km Converter
Kilometres per litre and litres per 100 kilometres describe the same thing from opposite ends, so converting between them takes nothing more than a division. This tool does that division for you and shows the MPG equivalents alongside, in case you need them for a car from another market.
The one thing to keep straight is direction. With km/L, bigger is better; with L/100km, smaller is better. A car doing 15 km/L uses 6.67 L/100km, while one doing 8 km/L uses 12.5, so the thirstier car has the lower km/L and the higher L/100km.
km/L to L/100km Converter
The conversion formula
L/100km = 100 ÷ km/L
Worked example: 12 km/L = 8.33 L/100km

Common questions
What is the formula?
L/100km = 100 ÷ km/L. Twelve km/L gives 100 ÷ 12 = 8.33 L/100km.
Why do some countries use L/100km instead of km/L?
Mostly regulation and habit. L/100km measures the fuel needed for a fixed distance, which makes it easy to add up and compare. km/L measures the distance you get from a fixed amount of fuel, which feels more natural at the pump.
Is 10 km/L good?
It's identical to 10 L/100km, which is middling: fine for a larger car or SUV in mixed driving, a bit thirsty for a small hatchback.
Can I use this for a motorbike?
Yes. Bikes are often quoted at 40 km/L or more, which is 2.5 L/100km or less. The arithmetic is exactly the same.
Does the fuel type change the conversion?
No. Petrol, diesel and LPG all use the same formula, because it only rearranges distance and volume.
