Coordinate Conversion

GPS2CAD.com is making available (at no cost) a Coordinate Conversion Web page (http://www.gps2cad.com/coordtrans/coordconvert.aspx) that converts world-wide grid and datum projections. It works for over 40 different datums and grids, including utm, nad-27, nad-83 and State Plane Coordinate System. For example, you can enter Latitude and Longitude from the popular wgs-84 format used by gps devices, and convert them to a utm or State Plane coordinate system.
