Jeremy is right! This stuff gets highly technical (not that I understand it). Be sure to check out the section on how to do

laplace transformations to correct for datum

One reason I got a GPS is I'm a techie and

interested in navigation in general and

cartography in particular. But the great thing about the "technical" stuff is that you don't need it for geocaching - most of the technical stuff revolves around taking the GPS "normal" (sans SA) accuracy of about

15 meters down to five or so mm. That's right - 5 mm. That's with them high dollar

government toys ....

Gentleman, Let your GPS unit do it for you.

Set your GPS to WGS 84, enter the numbers.

Reset your GPS to NAD27 or what ever datum your map is. Thats all there is to it.
