Convert Miles per Gallon (US) to Liters per 100 km

The mpg-to-L/100km conversion appears often when working with fuel economy data across different unit systems. 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.

Formula: Divide 235.214583 by the miles-per-gallon value. In equation form: L/100km = 235.214583 ÷ mpg.

One miles per gallon (us) equals approximately 235.214583 L/100km. This means you can multiply any mpg value by 235.214583 to get the equivalent in L/100km.

For instance, converting 100 mpg gives 2.352146 L/100km. Try different values using the quick-value chips or type directly into the input field.

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.
