Hint: Parsec is the unit of length used to measure the large distances to astronomical objects outside the solar system.
Megaparsec the larger unit of parsec.
1 megaparsec is equal to 1000000 parsec.

Complete step by step answer:
The parsec is the unit of length used to measure the large distances to astronomical objects outside the solar system approximately equal to 3.26 light years. Parsec is obtained by the use of parallax and trigonometry, and is defined as the distance at which one astronomical unit subtends an angle of one arc second. The Parallax method is the fundamental calibration step for distance determination in astrophysics.
Distances expressed in fractions of a parsec usually involve objects within a single star system. Like for example One astronomical unit, the distance from the sun to the earth is just under 5×106 pc. Generally astronomers use kiloparsec to express distances between parts of a galaxy or within groups of galaxies.
As per the question, mega means 106 it means that;
1 megaparsec = 1000000parsec.

Note: Similar to parsec there are many other units of measuring lengths and distances in space are kilometers, light year, lunar distance, astronomical units, giga meters. Generally, very large distances are being measured in giga and mega parsecs such as distances between two galaxies and clusters of galaxies. If we are to determine the number of stars in the sky their volume is measured in cubic kilometers.
