The two units are not compatible. A light year is a measure of distance. An arcsecond is a measure of arc or angle. To convert arc to length, you must first know the distance to what you are measuring.

How is a drgree of longitude or latitude further subdivided?

Each degree is divided into 60 minutes, and each minute is divided into 60 seconds. While the distance represented by a degree of longitude can vary with the latitude, each degree of latitude (north and south) is equal to 60 nautical miles, so one minute of latitude is equal to 1 nautical mile. (About 1.15 statute miles) One nautical mile is equal to 2026 yards, so one second of latitude is equal to 33.8 feet.
