You can do the reverse unit conversion from astronomical unit to megaparsecs, or enter any two units below:

megaparsecs to pe

megaparsecs to pike

megaparsecs to thou

megaparsecs to micrometer

megaparsecs to faust

The SI prefix "mega" represents a factor of
10^{6}, or in exponential notation, 1E6.

So 1 megaparsec = 10^{6} 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.

The astronomical unit (AU or au or a.u. or sometimes ua) is a unit of length. It is approximately equal to the mean distance between the Earth and Sun. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles).

The symbol "ua" is recommended by the Bureau International des Poids et Mesures, but in the United States and other anglophone countries the reverse usage is more common. The International Astronomical Union recommends "au" and international standard ISO 31-1 uses "AU".
