Convert Latitude and Longitude together between Degrees–Minutes–Seconds (DMS), Decimal Degrees, or a free-form coordinate string. All values follow the WGS84 datum (EPSG:4326) and ISO 6709 notation conventions. Provide one or both — whichever you leave blank is simply left blank in the result.
Coordinates are validated against the WGS84 ellipsoid (EPSG:4326). Latitude range: −90° to 90°. Longitude range: −180° to 180°.
Frequently Asked Questions
What coordinate formats are supported?
Degrees-Minutes-Seconds (e.g. 40°41'21.5"N), Decimal Degrees (e.g. 40.689306), and free-form strings in several common notations including colon-separated and space-separated formats.
Can I convert latitude and longitude at the same time?
Yes — enter both, or just one and leave the other blank; it's simply left blank in the result rather than causing an error.
What datum/coordinate reference system is used?
WGS84 (EPSG:4326), the standard used by GPS and most web mapping, following ISO 6709 notation conventions.
