Nobody can, because parsec is a measure of angular separation, not of time. That has always annoyed me.
Yep, just like a light year is a measure of distance, not time.
That used to bug me, too, but there is an explanation. In the Star Wars fictional universe, the Kessel run involves going through an area with a cluster of black holes that warp space. Depending on the path through the cluster, the distance differs. Only a really powerful hyperdrive permits one to take the shorter paths without getting sucked into a black hole. Thus, the distance for the Kessel run is shorthand for how powerful your ship’s hyperdrive is.
Not sure if this is cannon though.
Geek more. The boast was more about maneuverability and pilot skill than speed. Once you throw in hyperspace-jumps, it all becomes too silly to be annoying.
False. A parsec ("parallax second") is a measurement of distance - just like a light-year. In fact, a parsec is approx. 3.26 light-years.
It is based upon the fact that, in the course of six months, an object 3.26 light-years distant from Earth has an apparent displacement in position of one angular second in the sky - due to the Earth's revolving around the Sun, i.e., due to the parallax effect.
