About Coordinate Format Conversion
Convert geographic coordinates between Decimal Degrees (DD) and Degrees Minutes Seconds (DMS) formats. Essential for GIS, mapping, and navigation applications.
How to Use
Enter coordinates in either DD format (e.g., 39.9042,116.4074) or DMS format (e.g., 39°54'15.1"N, 116°24'26.6"E). The tool automatically detects the input format and converts to the other.
Supported Formats
DD format: decimal latitude and longitude separated by comma. DMS format: degrees, minutes, seconds with direction (N/S/E/W). Both latitude and longitude must be provided.
▶What is the difference between DD and DMS?
DD (Decimal Degrees) uses decimal numbers (e.g., 39.9042). DMS (Degrees Minutes Seconds) uses degree/minute/second notation (e.g., 39°54'15.1"N). Both represent the same location.
▶Why does my DMS input show as invalid?
Make sure your DMS format includes degrees (°), minutes ('), seconds ("), and direction letters (N/S/E/W). Example: 39°54'15.1"N, 116°24'26.6"E
▶How accurate is the conversion?
The conversion is mathematically exact. Decimal degrees are shown with 6 decimal places (about 0.1 meter precision). DMS seconds are shown with 1 decimal place.
