MEGAPARSEC
A megaparsec (Mpc) is a unit of distance that is equal to one million , 3.26 x 106 light-years or 3.085678 x1019 kilometers. The of galaxies is roughly a megaparsec in diameter.

A form of hydrogen under high pressure that is a good electrical conductor.
A distance of one million parsecs (approximately 3,262,000 ly or 2Ã-1019 miles) is commonly denoted by the megaparsec (Mpc). Astronomers typically measure the distances between neighboring galaxies and galaxy clusters in megaparsecs.
parsec
The distance to an object which has a parallax of one arc second. It is equal to 3.26 light years, or 3.1 x 1018 cm (see scientific notation). A kiloparsec (kpc) is equal to 1000 parsecs. A megaparsec (Mpc) is equal to a million (106) parsecs.
It is such a pain to write out all of those zeros that we'll just define a new unit of measure called the Megaparsec (Mpc), which is a million parsecs. There is also the unit of a Megalightyear, which is obviously a million lightyears.
unit when the angle between the Sun and the Earth, as seen from an object in space (a star for example), is one arcsecond The word parsec stands for "parallax of one arc second" One kiloparsec (kpc), is one thousand parsecs. One megaparsec (Mpc) is ...
