To US MPG:
US MPG = km/L × 2.35215
To UK MPG:
UK MPG = km/L × 2.82481
To L/100km:
L/100km = 100 ÷ km/L
Worked Example (500 km on 40 Liters):
1. km/L:
500 ÷ 40 = 12.5 km/L.2. US MPG:
12.5 × 2.35215 = 29.40 US MPG.3. L/100km:
100 ÷ 12.5 = 8.0 L/100km.Frequently Asked Questions
km/L is commonly used in Japan, India, Brazil, Mexico, Italy, Denmark, and several other regions as the primary measure of automotive efficiency.
