GPS Coordinate Converter
Convert GPS coordinates between decimal degrees (DD), degrees-minutes-seconds (DMS), and degrees-decimal minutes (DDM). Also shows the approximate UTM zone for the location.
GPS coordinates can be expressed in several formats. Different mapping tools, GPS devices, and navigation systems use different conventions.
Coordinate Formats:
- Decimal Degrees (DD): 40.7128, -74.0060. Used by Google Maps, most web mapping APIs, and databases.
- Degrees Minutes Seconds (DMS): 40° 42′ 46.08″ N, 74° 0′ 21.60″ W. Traditional format used in cartography and paper maps.
- Degrees Decimal Minutes (DDM): 40° 42.768′ N, 74° 0.360′ W. Used in marine navigation and many handheld GPS devices.
Conversion Rules:
- Latitude: -90 to +90 (South is negative, North is positive)
- Longitude: -180 to +180 (West is negative, East is positive)
- 1 degree = 60 minutes = 3,600 seconds
- At the equator, 1 degree of latitude ≈ 111.32 km
