Since this is a MapInfo mailing list, I suppose we should let you know that you can do this in MapInfo without any special add-ons or MapBasic applications (although you should use MapInfo 7.0 or later to preserve coordinate precision).
1. Import your list of coordinates into a table. 2. Use Table -> Create Points to create points from the latitudes and longitudes. Remember to select a Latitude/Longitude projection using the correct datum. 3. If you want to keep the Lat/Lon values in their columns, add two new X/Y columns to hold the UTM coordinates. 4. Open the table in a Map window. 5. Show the MapBasic window (Options ->Show MapBasic Window). 6. Use Map->Options to change the projection to UTM (or whatever projection suits your need). 7. A "Set Map Coordsys" statement will have been printed in the MapBasic Window. Delete the word "Map" so that it reads "Set Coordsys" and hit ENTER. 8. Use Table -> Update column twice to update the X and Y columns you created in step 3 (or the lat/lon columns if you didn't create any) with centroidX(obj) and centroidY(obj). You can also do this in one step by typing "Update mytable set xcol=centroidX(obj), ycol=centroidY(obj)" in the MapBasic window (where mytable is the name of the table you created, and xcol and ycol are the names of the destination columns).

I am going from lat/long to UTM. I have found several websites that allow for a single coordinate, but not one that I can get to work for a batch process. I have tried the Corpscon and Trailane Evaluation version and cant seem to get them to work. Are there any others?
