In HummPC open the Edit drop down menus and select “Preferences” and look for “Position format” and set this to the “dd.ddddd” setting. In GE open the Tools drop down menus and select “Options” and look for “Show Lat/Long” and select “Decimal degrees”. Both programs will now be displaying in the all degree format. GE will be using six decimal places while HummPC only uses fove so just drop off the last number from the GE waypoints. GE also uses positive and negative numbers to indicate North/East (positive Lat/Long) and South/West (negative Lat/Long). You can just manually enter in the waypoint numbers now.
If this is for many waypoints than I recommend doing as Rickie stated except to export the data from GPS Babel as a *.GPX type file so that HummPC can open it. The *.HWR file format is what the units use. HummPC is used to convert to/from the HWR to GPX file formats.
