Penn International 16sII full spool diameter?

[gstours]

 the Penn International 16sII ,  question?  what is the full lined spool diameter in inches.... as I know the gear ratio I then can do the math and determine how it compares in the (line gained per one revolution of crankhandle) line speed/cranking difficulty section with other reels I have...  as i saw some used reels for sale,,,,,,     What is the full spool diameter.....?
  I am assuming the following is correct for that determination; dia of spool X pie (3.314) X gear ratio = Line gained per one crank rev.

        I would like to hear from any interested persons with reply   thanks   GSTOURS.....

I use the formula a lot myself.  The correct pi number is 3.14159
