Hi,

there is a package "VectorAnalysis", you can load it with

Needs["VectorAnalysis`"]

and that does this for the most coordinate systems. You need only
look in the source code of the package to extend it to your
coordinate system if it is not already defined in
"VectorAnalysis`".

Regards
  Jens
