Yikes! I have used this site to help me find and hide caches. Please provide an example of an incorrect conversion, or at least the threads that discuss particular errors.

 

Thanks,

I just use my GPS!

 

Just make sure you change the format and datum to the correct units, make my UTM waypoint, then change back to normal position and format, and waypoint now shows correct conversion. It worked flawlessly on this cache:

Etna bog (GC3D79) by etna bog buckmasters 001 (3/2)

 

Some people are like Slinkies . . . not really good for anything, but you still can't help but smile when you see one tumble down the stairs.

I use USGS topo maps quite a lot for all my outdoor activities including Geocaching, so I use the UTM coordinate system in the NAD27 datum. Here's an example which is the location of my house. WGS84 coord's are N38°52.38588' W076°40.03086' Converted to NAD27 UTM coord's using my gps, the site I refered to, and other software I have tested, should be easting of 355341.11 and northing of 4303804.372 Jeeep.com gives me easting of 355342 and northing of 4303793 A northing error of 11 meters. Iv'e heard of worse errors but I don't recall if it was in these forums or maybe the sci.geo.satellite-nav newsgroup. It's been quite a while since I first noticed the errors and I haven't used the site since. There are different methods for transforming datums but I prefer to use one that agrees with my gps.
