3 GPS Formats
Decimal Degrees (DD: 40.7484, -73.9857), Degrees-Minutes-Seconds (DMS: 40° 44\' 54.24" N), and Degrees-Decimal-Minutes (DDM: 40° 44.904\' N).
Universal Standard
DD is used by Google Maps, OpenStreetMap, and most APIs. DMS is traditional (printed maps, surveying). DDM is preferred by aviation and marine navigation.

Frequently Asked Questions
A single floating-point value combining degrees, minutes, and seconds. 40.7484°N, -73.9857°E. Standard for software and APIs. Compact and easy to compute with.
Degrees, minutes, seconds. 40° 44\' 54.24" N. The traditional format on paper maps and used by surveyors. 1 minute = 1/60 degree, 1 second = 1/3600 degree.
Degrees and decimal minutes. 40° 44.904\' N. Used by aviation (ICAO) and marine navigation. Preferred because GPS receivers historically displayed minutes precisely.
6 decimal places in DD ≈ 0.11 m precision. 1 second in DMS ≈ 31 m. 0.001 minute in DDM ≈ 1.85 m. For most applications, 4-5 decimals in DD or 1 second in DMS is plenty.
Latitude: -90 (South Pole) to +90 (North Pole). Longitude: -180 to +180 (or 0 to 360). Greenwich Meridian = 0 longitude. Equator = 0 latitude.
