Liters per 100 Kilometers (L/100 km) to Gallons UK per 100 Miles (gal UK/100 mi) conversion

Use the Liters per 100 Kilometers (L/100 km) to Gallons UK per 100 Miles (gal UK/100 mi) 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 fuel-per-distance units describe the fuel needed for a fixed distance. A lower value means less fuel for the same trip.

Formula and direction

output = 0.354006 × 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 L/100 km converts to approximately 3.540062 gal UK/100 mi. A value of 20 L/100 km converts to approximately 7.080124 gal UK/100 mi. These are unit conversion examples, not estimates of what a particular vehicle will achieve.

Keep gallon definitions consistent

Use the U.S. liquid gallon, which is 3.785411784 liters, for any US label. Use the Imperial gallon, which is 4.54609 liters, for any UK label. These are different volume units, so an unlabeled mpg figure is ambiguous.

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.
