Just for the record
1 Parsec = 3.08568025 × 10 to the 16th power meters
A parsec is defined as the distance from the Sun which would result in a parallax of 1 second of arc as seen from Earth, where ly is a light-year. The word "parsec" is an abbreviation and contraction of the phrase "parallax second." Since distances of nearby objects can be determined directly using parallax observations combined with elementary geometry, the parsec was historically used to express the distances of astronomical objects from the Earth. This tendency has been carried over to some extent so that distances to objects are still often expressed in units of parsecs instead of light-years.
Why someone would insult another person by calling them a Jack-Ass eludes me. If it was intended as a jest as was my lighthearted Star Wars comment then I suggest you find a less offensive word. If it was meant as an insult then I suggest you need to reconsider the time your folks spent rearing you and act appropriatly.
