What Is km/L?
Kilometers per liter (km/L) is a fuel efficiency metric commonly used in many countries including Japan, India, and parts of South America. It measures how many kilometers a vehicle can travel on one liter of fuel. A higher km/L value means better fuel efficiency.
This metric is the inverse of L/100km (used in Europe and Australia). While L/100km tells you how much fuel you consume per distance, km/L tells you how far you can go with a given amount of fuel.

Frequently Asked Questions
How do I convert km/L to MPG?
Multiply km/L by 2.35215 to get US MPG. For example, 15 km/L = 15 x 2.35215 = 35.3 MPG. For UK (imperial) MPG, multiply by 2.82481.
What is a good km/L for a car?
For a standard gasoline car, 12-15 km/L is average. Above 15 km/L is good, and above 20 km/L is excellent. Hybrid vehicles can achieve 25+ km/L.
Why does my km/L change from tank to tank?
Fuel efficiency varies based on driving conditions (highway vs. city), weather, tire pressure, vehicle load, driving style, and fuel quality. Track your km/L over multiple fill-ups for a more accurate average.
