Convert liters per 100 km to miles per gallon quickly and accurately using this free online converter
Used for comparing car fuel economy across regions. Lower L/100km means better efficiency, while higher mpg means better efficiency — so the two scales move in opposite directions.
💡 Europe, Canada, and most of the world use L/100km; the US and UK use mpg (note: UK gallons are larger than US gallons, so UK mpg differs from US mpg).
mpg = 235.215 ÷ (L/100km)
Example: 1 L/100km = 235.215 mpg
Use L/100km for European and Canadian car listings; use mpg for US market comparisons.
Common uses: car specs, fuel cost estimation, and trip planning.
