Given a decimal longitudinal coordinate, such as -87.728055, it is trivial to convert it to DMS form. It will be necessary to determine whether it is a latitudinal or longitudinal coordinate in order to completely transform it. The method is as follows:
- , . - . 87,728055 = 87 .
- 60. . 0,728055 x 60 = 43,6833 = 43 .
- 60, . 0,6833 x 60 = 40,998 = 41 . 40 , , 41 .
