Hi people. I am looking for the equations for converting
s-parameter data to complex impedances. Does anyone
know where to find that?

I believe what you are looking for
Zin=Zo((1+S11)/(1-S11))
Zin being the complex impedance and Zo the measurement
reference impedance (50 Ohm usually) S11 being
the complex voltage reflection coefficient.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
