The DMS system also referred to as Degree-Minutes-Seconds is a system that is typically used by surveying a position that requires longitude and latitude.
In the DMS system, a degree is divided into exactly 6 minutes and each of those minutes is divided into 60 seconds.
One degree equals 60 minutes
One minute equals 60 seconds
One degree then equals 3600 seconds
Now if you want to convert any of this measurement you can just simply use the conversion method above for any given degree.
-317.06 degrees to DMS.
$$-317.06°$$ $$0.06(60)=3.6$$ $$0.6(60)=36$$ $$-317.06°=-317°3'36"$$
