Please provide an example of what you are attempting

I have coordinates for instance - Easting 387451.29, Northing 810524.08 and want to convert them to Longitude and Latitude.
Potentially without internet connection.

Possibly a solution here:

gps - Easting northing to latitude longitude - Stack Overflow.

Thats why I asked if there was an existing extension... I take it there isnt.

Steve, the equation is a little bit beyond my basic understanding, I was hoping an if there was extension it may simplify my quest.
Ill need to look for a workaround.

Thanks for the help.
