Frequently Asked Questions
Why is a UK gallon different from a US gallon?
They are historically different volume definitions, which is why UK and US MPG are calculated separately.
Why does a higher L/100km mean worse economy?
Because it measures fuel consumed per distance, the opposite direction from MPG, where higher is better.
