Converter: MGRS UTM WGS84 SK42

Coordinate Converter is a handy app for fast and accurate conversion of geographic coordinates between all the popular systems used by surveyors, cartographers, military personnel, hikers, and GIS professionals.

Enter a coordinate manually, import it from a file or a Google Sheet, instantly convert it to the format you need, check the result on the map, and export the finished data.

Why you need it:
• quickly convert coordinates from a GPS device, tracker, or map into the format you need;
• cross-check coordinates between different systems (for example, SK-42 and WGS84) for topographic and cadastral work;
• prepare a list of points or a polygon to upload into another app or GPS device;
• share coordinates with colleagues via a file or a Google Sheet;
• export results to formats ready for further work (CSV, KML, XLSX).

All calculations run locally on your device — coordinates are never sent anywhere, and the conversion itself doesn't require an internet connection.

The app is useful for surveyors, cartographers, GIS specialists, rescuers, hikers, hunters, and anyone who works with GPS coordinates, maps, and topographic data.

The free version contains ads and limits on the number of rows and points per conversion. The Pro version removes the ads and those limits.
