1 mile per gallon (US) equals 235.215 liters per 100 km. These units are inversely related — higher economy in one means lower in the other; the formula is L/100km = 235.2145833 ÷ (mpg)
L/100km = 235.2145833 ÷ (mpg)

1 mile per gallon (US) = — liters per 100 km (shown to 6 significant figures — the converter itself computes at full precision). The reverse factor is 1 liter per 100 kilometers = — mpg (us).
1 mpg = 235.215 L/100km; 10 mpg = 23.5215 L/100km; 100 mpg = 2.35215 L/100km. Use the full conversion table below for more reference values.
They measure the same thing in opposite directions. MPG is distance per fuel (higher = more efficient), while liters per 100 km is fuel per distance (lower = more efficient). They are inverses: 235.215 ÷ mpg gives L/100km in US units. Also note US and imperial gallons differ — 1 imp gal = 1.201 US gal — so UK mpg figures are about 20% higher for the same real consumption.
