Frequently Asked Questions
How do I convert L/100km to MPG?
Divide 235.215 by the L/100km figure. For example, 8 L/100km gives 235.215 ÷ 8 ≈ 29.4 US mpg. The relationship is symmetric, so the same division converts back.
Is a lower L/100km better?
Yes — lower is better, because it means less fuel burned to cover the same distance. This is the opposite of MPG, where higher is better, and it is the single most common confusion when comparing cars across markets.
What is a good L/100km figure?
Under 6 L/100km (about 39 mpg) is efficient for a petrol car, 6–8 is typical for a mid-size vehicle, and above 12 (under 20 mpg) is thirsty. Hybrids often reach 4–5 L/100km.
Why do regulators prefer L/100km?
Because it scales with actual fuel use. Improving from 12 to 10 L/100km saves far more fuel over the same distance than improving from 6 to 5, even though the MPG gain looks smaller — so the L/100km form makes real-world savings easier to compare.
