Coordinate conversion

Hi all

I have a Garmin GPSmap 60CSx its coordinates are E and N. I have been looking at google maps and google earth and the coordinates are S and E.
Does anyone know how to convert from S and E to E and N or what datum to use to change the input?

Thanks.

@Terry, if you search the dark recesses of the LINZ website, they have all the formulas to convert to and from different co-ordinate and projection systems.

The math behind it is next level. Ive often hoped someone would develop a simple android app that could convert GPS to topomap grid references...

Your gps is set to NZ Format, change to the USA format (like google is) punch in google earth coordinates then change back to NZ format and GPS will convert automatically coordinates back to NZ easting northings.

Thanks everyone for the replies, got it sorted. :thumbsup:
