Frequently asked questions
What coordinate formats does this converter support?
The tool converts between Decimal Degrees (DD), Degrees Minutes Seconds (DMS), and Degrees Decimal Minutes (DDM). It supports both cardinal direction notations (N/S/E/W) and signed positive/negative values.
How do negative values work in Decimal Degrees?
In Decimal Degrees, positive latitudes represent locations north of the equator, while negative latitudes represent the southern hemisphere. Positive longitudes lie east of the Prime Meridian, and negative longitudes lie west.
Can I paste the converted coordinates into Google Maps?
Yes. Google Maps accepts coordinates in Decimal Degrees (such as 37.7749, -122.4194) as well as Degrees Minutes Seconds directly in the search bar.
Is my coordinate data stored or sent to a server?
No. The coordinate conversion runs entirely in your web browser using client-side JavaScript. Your location data never leaves your device.
Is this coordinate converter free to use?
Yes, this tool is completely free with no usage limits, downloads, or account sign-ups required.
