ABOUT THIS CONVERSION
This page converts liters per 100 kilometers (L/100 km) to miles per US gallon (mpg US). Convertor4U first interprets the input using Liter per 100 kilometers's definition, then expresses the same quantity in Mile per US gallon. The result is calculated from the reciprocal fuel-consumption relationship, not from a rounded lookup table.
For comparing vehicle efficiency across regional specifications, an input of 7 L/100 km converts to 33.60208333 mpg US. Keep extra digits while calculating, then round only the final value to the precision the task actually needs.
One decimal place is usually adequate for vehicle comparisons. Keep more digits when estimating total trip fuel, then round to a practical volume. Published test-cycle numbers are standardized estimates, not guarantees.
US mpg and Imperial mpg use different gallons. The same numeric mpg therefore represents different efficiency. L/100 km is common in Europe and many other regions, while the US commonly uses mpg.
L/100 km runs in the opposite direction to mpg or km/L: a lower L/100 km value means better economy.
Definitions and sources are listed below. Calculations retain more precision than the default display and round only for presentation.
USEFUL ANSWERS
Enter the L/100 km value in the calculator. It applies the reciprocal fuel-consumption relationship and returns the equivalent in mpg US; the formula and common-value table are shown on this page.
Defined measurement relationships are calculated with decimal arithmetic from stored standards. The displayed answer may be rounded for readability. Currency results instead depend on the dated reference rate shown.
