I found a couple old threads on this topic:
thread820-140933
thread407-23283
Neither seemed to answer the question regarding what GD2 vs. WR2 mean.
The best answer I have found is that GD2 is what mass moment of inertia is called in SI units and it would typically have units of kg*m^2. WR2 is used to designate imperial units and would typically have units of lbf*in^2 or lbf*ft^2.
There is an excellent link here: Link that goes further into the subject.
Be careful when trying to convert between them as I think the old threads erroneously give a conversion between the two. It is obviously highly dependent on which units you pick!
