A Parsec (symbol: pc) is a unit of length, used to measure the distance between stars.
The name parsec stands for "parallax of one second of arc", and allows calculating distances to nearby stars using simple observation and trigonometric parallax (apparent motion of an object due to change of position of the observer). It is one of the oldest Terran methods for measuring the distances to stars. A parsec is based on a baseline of 1 Astronomical unit.

The Solomani define one parsec to be the distance from the Terra to a star that has a parallax of 1 arcsecond, and equals 3.261 light-years or 206,265 Astronomical units. By coincidence this distance is very close to the maximum distance a jump-1 drive can jump. Because of this, 'parsec' has become the standard word used for this distance within the Imperium.
Other races, using the orbital distance of their home world and different definitions of an arc second would derive different values for a parsec, but these wouldn't be Imperial parsecs.
