Frequently Asked Questions
- Is this coordinate converter free?
- Yes, completely free with no signup and no usage limits.
- Does my data leave my device?
- No. All conversions run in JavaScript inside your browser. No data is sent to any server.
- Does it work on mobile?
- Yes. The converter is mobile-first and works on iPhone Safari and Android Chrome.
- What is the difference between DD, DMS, and DDM?
- DD (decimal degrees) expresses latitude and longitude as decimals (e.g. 51.5074°N). DMS (degrees-minutes-seconds) uses the traditional format (e.g. 51°30'26"N). DDM (degrees-decimal-minutes) keeps whole degrees but uses decimal minutes (e.g. 51°30.444'N).
- Which format does Google Maps use?
- Google Maps accepts all three formats. The default display uses decimal degrees, but you can paste DMS coordinates into the search bar and it will recognise them.
