Mpg ↔ L/100km
CopiedAbout this mpg ↔ L/100km converter
Fuel economy both ways. US mpg and liters per 100 km move inversely — higher mpg is lower L/100km.
L/100km = 235.214583 / mpg (US). mpg = 235.214583 / L/100km. The constant comes from gallons and kilometers unit definitions.
Not a trip cost calculator and not UK imperial mpg (different gallon). Driving style dominates real tanks.
How do you convert US mpg to L/100km?
L/100km = 235.214583 ÷ mpg. That uses the US gallon (3.785411784 L) and the international mile (1.609344 km).
Is this UK mpg?
No. UK gallons are larger. Use the UK/US mpg converter for that pair.
Is this a driving recommendation?
No. It only converts the two fuel-economy units.
