WGS84 Lat/Lon Converter

About This Tool

The tool accepts WGS84 geographic coordinates and outputs both decimal degrees and DMS representations for latitude and longitude. Conceptually, it bridges two common coordinate representations used across GIS, surveying, and mapping systems. Users supply lat and lon in either decimal degrees or DMS, and the tool performs precise conversions in real time. The system emphasizes accuracy, validation, and clear formatting so coordinates can be copied into datasets, maps, or APIs without normalization steps. Unique value comes from dual-format outputs in a single pass, minimizing context switching between formats and reducing the chance of conversion errors. Use cases include data entry for shapefiles, GIS layers, or field notebooks, and developer workflows requiring programmatic integration with coordinate data. Core features include robust range checks, handling of N/S and E/W signs, and explicit datum assumption (WGS84). The tool does not perform datum shifts or projections beyond the WGS84 geographic frame, ensuring predictable results when only lat/lon are required. Outputs include lat_decimal_out and lon_decimal_out (decimal degrees) and lat_dms_out and lon_dms_out (DMS strings). The interface supports both input formats and can be integrated into data pipelines that require consistent cross-format coordinates across platforms.
