Longitudes and latitudes are used to locate places on a map. The Greenwich meridian is the starting point for al longitude readings. Lines to the East of Greenwich meridian are measured in degrees and readings are followed by letter E, example: 35°E and vice-versa. All latitudes above the equator are measured in degrees north of the Equator and readings are followed by letter N. example: 15°N. Readings measured to the south of the equator are followed by letter S. example: 15°S. To be more accurate, we use degrees and minutes           .

1 degree is equal to 60 minutes.

For example;

-Cameroon is located on latitude 5°00'N and longitude 12°30'E,

-Yaoundé - 3°51'N and 11°31'E,

-Bertoua - 4°34'N and 13°42'E,

6Douala - 4°05'N and 9°45'E.
