C'est simple !!!
1 degré = 60 minutes
1 minute = 60 secondes

Exemple : convertir 29,556° en degrés, minutes et secondes d'arc.

29,556 = 29 + 0,556 ==> 29°
0,556 x 60 = 33,36 = 33 + 0,36 ==> 33'
0,36 x60 = 21,6 ==> 21,6"

Bilan : 29°33'21,6".

En fait, le nombre de départ est donné au 1/1000 près, et 1/1000 est plus grand que 1", donc il vaut mieux arrondir : 29°33'22".
