50g

Hi all;
I'm new to this group, I joined it in hopes of getting some help 
learning the new machine. I've been using a TI 86 for years, time to 
move up but the user manual isn't very helpful! I think I'm OK with 
RPN but some functions that SHOULD be quick and easy (like the TI) are 
turning out not to be. Elementary things like unit conversions (ex: 
convert yd^3 to m^3) seem to be very exhaustive to accomplish!
My primary use for this calculator is in doing survey calcs (bought 
the DZign software pac with the 50g).
All comments, suggestions gratefully accepted.
Thanx
Richard
