You can do the reverse unit conversion from Gly to megaparsec, or enter any two units below:
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.
One gigalight-year, abbreviation "Gly", is one billion light-years — one of the largest distance measures used. One gigalight-year equals 306.601 million parsecs, or roughly one-thirteenth the distance to the horizon of the observable universe (dictated by the cosmic background radiation). Gigalight-years are typically used to measure distances to supergalactic structures, such as clusters of quasars or the Great Wall.
