1 mpg (US) ≈ 0.4251 km/L. Edit either value to convert instantly.
Conversion formula
km/L = 100 / (235.214583 / (mpg (US)))1 mpg (US) ≈ 0.425144 km/L
mile per US gallon (mpg (US))
US miles per gallon measures distance per 3.785411784 L; consumption in L/100 km equals 235.214583 divided by mpg, so 30 mpg ≈ 7.84 L/100 km.

kilometer per liter (km/L)
Kilometers per liter measures distance traveled using 1 L; L/100 km = 100 ÷ (km/L), so 20 km/L = 5 L/100 km.

Frequently asked questions
How many kilometers per liter are in 1 mile per US gallon?
1 mpg (US) ≈ 0.4251 km/L. km/L = 100 / (235.214583 / (mpg (US)))
How do I convert mpg (US) to km/L?
km/L = 100 / (235.214583 / (mpg (US)))
Why does this conversion need more than multiplication?
Fuel economy and fuel consumption are reciprocal measures. Divide the conversion constant by the value; zero has no finite result.
