Liters per 100 Kilometers to Miles per Imperial Gallon Converter
mpg (imp) = 282.4809363 ÷ L/100 km
An inverse measure: 5 L/100 km is twice as efficient as 10 L/100 km, not half.
1 liter per 100 kilometers equals 282.481 miles per imperial gallon
How to convert liters per 100 kilometers to miles per imperial gallon
Distance per fuel (mpg or km/L) increases with economy; fuel per distance (L/100 km) decreases. Converting between these forms is reciprocal, requires a positive value and depends on whether a gallon is US or Imperial.
mpg (imp) = 282.4809363 ÷ L/100 kmThese units run in opposite directions: one measures distance per unit of fuel and the other fuel per unit of distance. Dividing 282.4809363 by the liter per 100 kilometers figure gives the mile per imperial gallon figure, and dividing it back returns the original — which is why a lower number is better on one scale and worse on the other.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
