Your results

Kilometres per litre15 km/L
Equivalent L/100km6.67 L/100km

Calculation breakdown

km/L
km/L = distance travelled / litres used

Worked example

Travelling 300km on 20L of fuel gives 15 km/L.

Assumptions

  • Assumes a full tank-to-tank fill for accuracy.
  • Higher km/L means better efficiency.

How this calculator works

Divide the distance travelled by the litres of fuel used to find your vehicle's kilometres per litre, a straightforward efficiency figure often used for motorcycles and smaller engines. Higher figures mean better fuel efficiency for the distance covered.

Frequently asked questions

How is this different from L/100km?

Km/L expresses distance per litre while L/100km expresses litres per 100km travelled; they are inverse measures of the same underlying efficiency.

Is this useful for motorbikes?

Yes, km/L is a common way Australian motorcycle owners describe fuel efficiency.

Does driving style affect this figure?

Yes, aggressive acceleration, heavy loads and short trips with a cold engine all reduce kilometres achieved per litre.
