Right. So I've got land survey coordinates, with the Lo. WG29 degree offset (Pretoria).

(1) How do I convert this to WGS coordinates so that I can load it into my GPS and view it on Google Earth etc.? I've read that I need to download ModelMaker Conversion Tool, which does not work on my MacBook. Eina. Tried it on a Windows 7 PC at the office and it crashes there as well.

(2) I understand the point is that Surveyors use projection coordinate systems, for greater accuracy. Am I correct in assuming that the numbers I have is in meters? For instance if a landmark is 45 940.17 and 58 309.93 with 2 800 000.00 offset (for example) this is all meters from the reference point?

(3) So is there a tool in Google Earth that can convert this to WGS coordinates that my GPS can understand? There is a display option that seems to refer to a US Geological standard, not much use here.

The goal is twofold: I want to se how close I can come to the survey points in my area, and of course it would be great to know exactly where my border are.
