GPS Coordinate Converter

Decimal degrees like 40.7128, -74.006; degrees minutes seconds like 40 42 46 N, 74 0 21 W; and degrees decimal minutes like 40 42.768 N, 74 0.36 W. Degree, minute and second symbols, the words deg, min and sec, and N/S/E/W hemisphere letters are all understood.

Decimal degrees equal degrees plus minutes divided by 60 plus seconds divided by 3600. For example 40 degrees 42 minutes 46 seconds is 40 + 42/60 + 46/3600, which is about 40.7128. South and West coordinates are negative.

DMS (degrees minutes seconds) splits the fraction of a degree into whole minutes and seconds, like 40 42 46. DDM (degrees decimal minutes) keeps the minutes as a decimal, like 40 42.768, and is common in marine and aviation GPS units.

No. You can use a minus sign for South and West instead, for example -33.8688, 151.2093. If you do use hemisphere letters, the tool assigns latitude and longitude automatically, so the order does not matter.

Latitude runs from -90 to 90 degrees and longitude from -180 to 180 degrees. Anything outside those ranges is rejected as invalid.

No. The conversion runs entirely in your browser, so the coordinates you enter never leave your device.
