Convert Kilometers per Liter to Miles per Gallon (US)

Converting Kilometers per Liter (km/L) to Miles per Gallon (US) (mpg) is a common task in fuel economy measurements. Fuel economy is expressed differently worldwide: the US uses miles per gallon, Europe often uses liters per 100 kilometers, and efficiency can also be stated as kilometers per liter.

To convert, multiply the kilometers-per-liter value by 2.35214584. Written as an equation: mpg = km/L × 2.35214584.

One kilometers per liter equals approximately 2.352146 mpg. This means you can multiply any km/L value by 2.352146 to get the equivalent in mpg.

Worked example: 25 km/L = 58.803646 mpg. Enter your own value in the converter above for instant results.

Common mistake: Higher mpg means better efficiency, but lower L/100km also means better efficiency — these scales run in opposite directions, so do not compare the numbers directly without converting.
