The TatukGIS Coordinate Calculator interactively converts coordinates of a point between coordinate systems. More than 4,800 predefined geographic and projected coordinate systems can be simply selected from the list or found using the handy search tool. Alternatively, a coordinate system can be user-defined from the 150+ supported projections and 900+ supported datums. As with other TatukGIS products, the support for coordinate systems is state-of-the-art, reflecting EPSG codes and OpenGIS WKT definitions.

The Coordinate Calculator for Windows is available as a free download from the TatukGIS web site. The Coordinate Calculator for macOS can be purchased for a small fee from the Apple Mac App Store.

For batch conversion of large x,y coordinate datasets (for many points) between coordinate systems in a single operation, refer to the CSConverter script in the TatukGIS Editor product. CSConverter is one of many useful scripts packaged with the Editor.
