Simple Coordinate Conversion (Taiwan Only) is a free Chrome add-on developed by Marcus. It falls under the Browsers category and specifically the Add-ons & Tools subcategory. This program allows users to convert coordinates between the WGS84, TWD97, and TWD67 modes. With just a few clicks, users can obtain the converted coordinates and even copy them for further use. It is important to note that the output data provided by this add-on is for reference purposes only and should not be used for cadastral or precise positioning measurements.

The latest version, v1.0.1, has addressed and resolved issues related to the display of query results. Users are encouraged to provide feedback and suggestions in the comments section for any questions or ideas they may have.
