1 mile per gallon (imp) equals 282.481 liters per 100 km. These units are inversely related — higher economy in one means lower in the other; the formula is L/100km = 282.4810531 ÷ (mpg (imp))
L/100km = 282.4810531 ÷ (mpg (imp))

1 mile per gallon (imp) = — 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 (uk).
1 mpg (imp) = 282.481 L/100km; 10 mpg (imp) = 28.2481 L/100km; 100 mpg (imp) = 2.82481 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.
