Kilometers per Liter (km/L) to Miles per Liter (mi/L)

Kilometers per Liter (km/L) to Miles per Liter (mi/L) conversion

Use the Kilometers per Liter (km/L) to Miles per Liter (mi/L) converter to compare vehicle figures reported in different fuel units. Enter a positive value, choose a precision from 0 to 12 decimal places, and select Submit. Read the output with its complete destination label. Both distance-per-fuel units describe how far a vehicle travels on one unit of fuel. A higher value means more distance for the same fuel.

Formula and direction

output = 0.621371 × input. This factor is rounded here for readability; retain the underlying unit definitions for further calculations. Both units describe the same kind of ratio, so this conversion uses a constant multiplier. Doubling the source value doubles the destination value.

Worked examples

A value of 10 km/L converts to approximately 6.213712 mi/L. A value of 20 km/L converts to approximately 12.427424 mi/L. These are unit conversion examples, not estimates of what a particular vehicle will achieve.

Keep gallon definitions consistent

The international mile equals 1.609344 kilometers. Keep the distance and fuel units together when copying values from a vehicle display or a specification sheet.

Frequently asked questions

Can I enter zero?

This converter requires a positive input and rejects zero or negative values. A reciprocal calculation divides by the input, so zero has no finite converted result. Use a positive measured value for fuel comparisons.

Does converting make two vehicle tests comparable?

It puts their units on the same basis. It does not remove differences in speed, route, weather, driving style, or test procedure. Keep those conditions in mind when comparing the converted figures.
