FIll percentage for GRC and RMC

[Pressure]

Are the interior diameters for GRC and RMC the same? I'm making sure that my 40% fill is not exceeded when I use GRC. It seems that since the NEC does not have a specific table in chapter 9, other than the one for RMC, that I can use it for my calcs?

Those are different terms for the same raceway

Yes RMC comes is several types of metal, GRC or galvanized rigid conduit is just one type.
