Convert fuel economy between L/100km, km/L, MPG (US), and MPG (UK). These measure the same thing differently. Lower L/100km = better. Higher km/L or MPG = better. 1 L/100km = 100 km/L inverse. 1 L/100km ≈ 235 US MPG (not directly comparable due to different gallon sizes). Sri Lanka and India use km/L or L/100km.

🤔 How Does This Work?
All values converted to L/100km as base unit
1 US MPG = 235.214 L/100km (inverse)
1 UK MPG = 282.481 L/100km (inverse)
1 L/100km = 100 km/L (inverse)
❓ Frequently Asked Questions
Is L/100km or km/L better for comparing cars?▼
Both measure the same thing. L/100km: lower is better (less fuel for same distance). km/L: higher is better (more distance per litre). L/100km is used in Europe, Australia, and increasingly Asia. km/L is traditional in India and Sri Lanka. MPG (miles per gallon) is used in USA and UK. Our converter handles all.
What is a good fuel economy for a car?▼
In Sri Lanka, a fuel-efficient small car achieves 18-25 km/L (4-5.5 L/100km). Average car: 12-15 km/L (6.5-8 L/100km). SUV: 8-10 km/L (10-12 L/100km). Hybrid: 20-30 km/L (3-5 L/100km). These vary significantly by driving conditions — city driving uses 20-30% more fuel than highway.
