Convention for the symbol of Dielectric Constant

  1. Nov 13, 2014 #1
    I have come across the dielectric constant represented by two variants of epsilon. Is there any convention behind the two variants such that:
    [itex]\varepsilon[/itex] is the SI Dielectric Constant
    [itex]\epsilon[/itex] is the CGS Dielectric Constant
    or does it really depend on the writer and how frisky they feel?

    There is no famous convention but people can use such a thing as long as they state what they mean by each explicitly. So if nothing is said about such a convention being used, then there is nothing behind it.(Of course assuming a reasonable author!)

    Maybe I could start a new convention! XD
