The UDUNITS package can be built with a Fortran-77 compatible API.  The
API is implemented in C but is designed to be callable from Fortran-77
code.  Because of this, your first question devolves into your second
question:

I know that Fortran-90 code must be able to use Fortran-77 code because
the netCDF package does this.  The netCDF Fortran-90 API is implemented
using the netCDF Fortran-77 API.

I suggest that you take a look at the netCDF package on your system.
Contact me if you have any questions.
