Question : Problem: How to determine conduit fill for Cat 6 cable?

Hello Experts,
   Is there a way to determine how many Cat 6 cables I can fit in a metal conduit with 2" diameter? How do you calculate using different fill pecentages such as 40% and 50%.  I have found different charts online but they require knowing what the kcmil or awg of the cable is.  How do I determine those measurements?
