My problem is my lack of knowledge on the historical development of the constant used for the permittivity of free space. I know instead of asking the question I should read Wiki on the history of "permittivity" and I did.
The article in some some sense seems to imply Maxwell's Equations were necessary in order to complete the value of the constant but I am not sure I understand why so this prompted me to ask the above question. I will keep reading the Wiki article again and again till I understand it but thought I would ask the question.
