The standard coordinate system for GPS. Most map services use WGS84.
1 degree = 60 minutes, 1 minute = 60 seconds. e.g., 37° 30' 30" = 37.5083°
Latitude ranges from -90 to 90, longitude from -180 to 180. Positive values are North/East, negative are South/West.
6 decimal places gives approximately 10cm accuracy. Generally, 5 decimal places is sufficient.
How to convert decimal coordinates to degrees (°), minutes ('), and seconds (").
Example: 37.566535° → 37° 33' 59.53"
Formula to convert DMS coordinates to decimal degrees.
DD = Degrees + (Minutes ÷ 60) + (Seconds ÷ 3600)
Example: N 37° 33' 59" + E 126° 58' 41" → 37.566389, 126.978056
A tool that converts between addresses and GPS coordinates (latitude/longitude). Enter an address to get coordinates, or enter coordinates to find the address. You can also select coordinates directly by clicking on a map. Supports conversion between DD (decimal degrees) and DMS (degrees, minutes, seconds) formats.
Choose a method
Choose your preferred method: search by address, search by coordinates, click on the map, or current location.
Enter value
Enter an address or enter latitude/longitude coordinates. Or click directly on the map.
Check results
The converted coordinates (DD, DMS format) or address are displayed and a marker is displayed on the map.
Utilization of coordinates
You can copy coordinates or use append mode to save multiple coordinates to a list and export them as CSV. For bulk data, check the sheet and latitude/longitude column in ‘Excel/CSV Import’ and download it as value-only XLSX.
DD (Decimal Degrees) expresses coordinates as decimal points, such as 37.5665, and DMS (Degrees Minutes Seconds) expresses coordinates in degrees, minutes, and seconds, such as 37° 33' 59".
You must allow location permission in your browser. It only works in an HTTPS environment. Please check location permissions in your browser settings.
The accuracy is approximately 1m to 5 decimal places, and approximately 10cm to 6 decimal places. For general purposes, 5 digits are sufficient.
When you enable append mode, coordinates will be added to the list each time you click on the map. This is useful when collecting coordinates of multiple points at once.
Supports XLSX, XLS, CSV, TSV, and copied tables. The header and latitude/longitude columns are automatically suggested and can be changed manually. Process up to 5,000 rows of data at a time.
No. Spreadsheet files, cell values, and transformation coordinates are processed only within the browser and are not transmitted or stored on servers, analysis tools, or local storage. Only when you perform an address search directly will the address you enter be sent to an external map service.
Distinguish between valid, warning, and error in the preview while maintaining row numbers and original order. The Errors sheet for the downloaded XLSX also includes the original line number and reason for the error.
WGS84 is the standard coordinate system for the GPS satellite navigation system and is used by most map services such as Google Maps and Naver Maps.
