Convert degrees-minutes-seconds (DMS) notation to decimal degrees
Accepts DMS strings in various formats with symbols or spaces
Returns high-precision decimal degree coordinates
Output directly usable in mapping APIs and GIS software
Convert coordinates from DMS system to Decimal Degrees system
Enter coordinates in degrees, minutes, seconds form — for example 116°24'14"E or 39 54 15 N. Symbols, plain spaces, and mixed separators are all accepted.
Click Convert and the tool parses the DMS parts, applies degrees + minutes/60 + seconds/3600, and applies the hemisphere letter as a sign.
Copy the decimal degree result, ready for mapping APIs and GIS software. Conversion is free, instant, and happens right in the page.
AIt tolerates the common variants: degree/minute/second symbols (116°24'14"E), space-separated numbers (39 54 15 N), and entries with or without hemisphere letters. You can also use negative signs instead of S/W.
AEach unit is expressed as a fraction of a degree: decimal = degrees + minutes/60 + seconds/3600. For 116°24'14"E that gives 116 + 24/60 + 14/3600 = 116.40389°, and the hemisphere letter decides the final sign.
ASouthern latitudes (S) and western longitudes (W) are represented as negative decimal degrees by convention. If you entered 33°52'8"S, the output -33.86889 is the same location expressed the way most software expects it.
