Coordinate format converter
Convert decimal degrees and degree-minute-second coordinates.
How to use Coordinate format converter
Coordinate format converter turns a latitude and longitude between decimal degrees and degrees, minutes and seconds. Enter each value as a decimal number or as space-separated D M S followed by a hemisphere letter. The result shows both decimal coordinates and DMS notation with seconds rounded to 2 decimal places.
- Enter the requested values in the settings panel.
- Set latitude: decimal or d m s n/s, longitude: decimal or d m s e/w.
- Run coordinate format converter, review the output, then use the available copy or download controls.
What this tool supports
Convert decimal degrees and degree-minute-second coordinates.
- Latitude: decimal or D M S N/S
- Set this value for your task.
- Longitude: decimal or D M S E/W
- Set this value for your task.
Limits and processing
Local bounded calculations. Numeric inputs must be finite and within the visible ranges. Lists and tables have operation-specific limits. Models, estimates and supplied rates must be checked against your intended use.
Frequently asked questions
How do I convert DMS coordinates to decimal degrees?
Enter the latitude as degrees, minutes and seconds separated by spaces, followed by N or S, for example 40 26 46 N, and the longitude with E or W. The decimal values appear in the result.
Should I type the degree symbol in the coordinate converter?
No. Separate degrees, minutes and seconds with spaces and add the hemisphere letter at the end. Minutes and seconds must each be below 60.
How are south and west coordinates shown in decimal?
Coordinates in the southern or western hemisphere become negative decimal numbers. You can also enter a negative decimal directly, and the DMS output adds S or W.
Where is my input processed?
This operation processes its source in your browser. Copy and download are explicit actions; source input is not saved in an account or history.
What are the input limits?
Local bounded calculations. Numeric inputs must be finite and within the visible ranges. Lists and tables have operation-specific limits. Models, estimates and supplied rates must be checked against your intended use.
