Aug 15, 2011 · This calculator determines the minimum octane rating, also known as the knock index, by the formula (R+M)/2. Octane rating number is defined as a value used to indicate the resistance of a motor fuel to knock. Octane numbers are based on a scale on which isooctane is 100 (minimal knock) and heptane is 0 (bad knock).
