How fuel economy converter works

L/100 km is inverse consumption, not a simple linear unit. Convert km/L to L/100 km by dividing 100 by the km/L value.

Example formula: 100 ÷ km/L = L/100 km

Frequently asked questions

Why does a lower L/100 km mean better economy?

It measures fuel consumed for a fixed distance, so using fewer liters is more efficient.

No. The Imperial gallon is larger, so the same vehicle has a higher numeric Imperial MPG.
