Why is this not a simple multiplication?
One unit measures the quantity directly and the other measures its inverse, so a larger value in one means a smaller value in the other. That is why the formula divides a constant by your value.
Is this L/100 km to mpg converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
