Only as a side note, one of the good things of the (ISO 216) A format for similar calculations is that the largest one, A0, is defined as being 1 m2 (841x1,189 mm) and since smaller formats are obtained halving the size, the common A4 is the 4th halving, thus it is 1/16th of the A0. A sheet of A4 paper 80 gr/m2 weights 5 grams, easier. Back to the link, I lost the Author when he uses the "i" and Times New Roman, I would have found the experiment more meaningful if he used a fixed spaced font and thus could print something more than i's, and then there is the issue about non-printable characters, if you really want to "print" a program you will need hex, which would at least double the weight of a byte.
