You can do the reverse unit conversion from MPC to megalight-year, or enter any two units below:
One megalight-year, abbreviated "Mly", is one million light-years, or 306,601 parsecs. Megalight-years are typically used to measure distances between neighboring galaxies and galaxy clusters.
The SI prefix "mega" represents a factor of 106, or in exponential notation, 1E6.
So 1 megaparsec = 106 parsecs.
The definition of a parsec is as follows:
The parsec (symbol pc) is a unit of length used in astronomy. It stands for "parallax of one arc second", and is approximately 19,131,554,073,600 (19 trillion) miles.
