Need help interpreting these coordinates

@geeoddmike - Thanks!

@norman-oklahoma - Downloaded the free version and got the data points. Thanks!

This poster is completely wrong!!! It is UTM Zone 24S. 

What an idiot. Sheesh.

@dave-karoly

I use chrome at work and they wouldn't appear.  I use firefox at home and they appeared fine.  Just another reason chrome is inferior.  ???? 

@geeoddmike - You still have trouble seeing images on this forum?

A pair of coordinates could be:

343825.1072
9688158.7381

The tool you sent me request some additional data:

• Datum (of input and output coordinates) - options: [NAD83] or [NAD27]
• Longitude Referenced system - options: [WEST] or [EAST]

Either way, once I put in the data and press submit the tool gives me hidden data:

===========================================================
          North(Meters)     East(Meters)     Datum     Zone
 INPUT =  343825.1072       9688158.7381     NAD83     24
 ===========================================================

 LATITUDE         LONGITUDE         ZONE  CONVERGENCE  SCALE FACTOR
 DD MM SS.sssss   DDD MM SS.sssss         DD MM SS.ss  
 --------------   ---------------   ----  -----------  ------------
 ** ** ******** S *** ** ******** W  24  - * ** *****  **********

I do see that the website says " This tool has been superseded and replaced by NGS Coordinate Conversion and Transformation Tool (NCAT) "

@geeoddmike - Got it! I used http://www.rcn.montana.edu/Resources/Converter.aspx

Thanks for the help!

Well with your help I found the correct coordinate system, and can now use this website to convert:

Now I can find the terrain on Google Maps. And with AutoCAD I can measure distances, so I can start planning a construction of some sort.

Thanks a million all, for you help!!
