Examples
30 mpg (US) ≈ 7.84 L/100km10 km/L = 10 L/100km40 mpg (UK) ≈ 33.3 mpg (US)
Miles per gallon and km/L measure distance per fuel, so higher is better. L/100km measures fuel per distance, so lower is better; the conversion is an inverse, not a simple multiplication. US and UK gallons differ, so US mpg and UK mpg are not the same.
