To emphasize the point more strongly, I'd have stated it "this number NOT ONLY converts from base ten to base two, BUT ALSO multiplies by 1200 to convert from octaves to cents". The number ONLY to convert from base 10 to base 2 (which describes a frequency multiplier as a number of octaves between the two pitches) is the reciprocal of the base-10 log of 2, which is roughly 3.322.
