FAQ
Why are L/100km and mpg reciprocal?
L/100km measures fuel per distance (lower is better) while mpg measures distance per fuel (higher is better), so they invert via constants: 235.215/mpg(US) = L/100km.
US vs UK mpg difference?
The imperial gallon is larger so UK mpg reads higher for the same car: 235.215/mpg(US) = 282.481/mpg(UK) — always check which system.
