Frequently asked questions

Why does L/100km decrease as efficiency improves, while MPG increases?
L/100km measures fuel consumed per unit of distance -- less is better. MPG measures distance achieved per unit of fuel -- more is better. They are reciprocal concepts, so a very efficient car might be 4.5 L/100km and 52 US MPG at the same time.
How do I convert 8 L/100km to MPG?
Use the formula: US MPG = 235.2145833 / L/100km. So 235.2145833 / 8 = approximately 29.4 US MPG.
What is km/L and where is it used?
km/L is the distance travelled per litre of fuel, conceptually similar to MPG. It is commonly used in Japan, India, and some other Asian countries. A car achieving 15 km/L gets about 35 US MPG or 6.67 L/100km.
