What is DMS and DD?

Degrees, Minutes, Seconds (DMS) format expresses latitude and longitude using a combination of degrees (°), minutes (′), and seconds (″). It is commonly used in surveying, cartography, and traditional navigation.

Decimal Degrees (DD) format simplifies coordinates into a pure decimal number, making it ideal for modern digital applications such as GPS devices, GIS platforms, remote sensing software, and mapping APIs.

How It Works

• 📍 Input a coordinate either in DMS (e.g., 37°42′45.95″ N) or in DD (e.g., 37.712764).
• 🔄 Automatic two-way conversion:
  • DMS → DD
  • DD → DMS
• 🛠️ Real-time formatting ensures clean and standardized output as you type or paste values.
• ⚙️ Error validation to prevent mistakes like wrong degrees, minutes, seconds, or missing direction (N/S/E/W).

Export Options

After converting your coordinate, you can easily export the result into several widely used geospatial data formats:

• 📄 TXT — Simple text format for quick sharing or documentation.
• 📑 CSV — Table format for spreadsheets and database import.
• 🛰️ WKT (Well-Known Text) — For GIS software like QGIS and ArcGIS.
• 🌎 GeoJSON — Ready for web mapping and spatial APIs like Leaflet or Mapbox.
