Use Google Maps to find coordinates
Example:
Latitude: 40 Deg. 43 min. 21 sec.
Longitude: -82 Deg. 31 Min. 52 Sec.
To find the city that matches these coordinates, enter the following into Google Maps search field: 40 43' 21" -82 31' 52" and the GPS coordinate will show up in Google Maps
Additionally, if your latitude and longitude numbers are in decimal format, like say, 40.7225 -82.5331 there is no need to convert over to the degree minutes, seconds, notation. Google Maps will give you your coordinates.
