About Coordinate Formats

Decimal Degrees (DD) express latitude and longitude as decimal numbers, such as 47.6062, -122.3321 for Seattle. This format is standard in GPS devices, mapping APIs (Google Maps, Leaflet), and GeoJSON data.

Degrees, Minutes, Seconds (DMS) break each coordinate into direction (N/S/E/W), degrees, arc-minutes, and arc-seconds, e.g. 47° 36' 22.32" N, 122° 19' 55.56" W. This traditional format is still common in nautical charts, hiking maps, and survey data.

Converting between them is straightforward: decimal degrees = degrees + minutes/60 + seconds/3600. For south or west coordinates, the result is negative.

Frequently Asked Questions

Decimal degrees equal degrees plus minutes divided by 60 plus seconds divided by 3600. For south or west coordinates, the result is negative.

Address lookups are powered by OpenStreetMap's Nominatim service, which is generally accurate to street level in well-mapped areas, though coverage varies by region.
