Parsec (pc). A parsec is about 3.26 light years and is used by astronomers for distances between stars.
Astronomical unit (AU). An astronomical unit is the average distance from the Earth to the Sun, about 149.6 million kilometers.
There are 206,265 astronomical units in one parsec.
Multiply the number of parsecs by 206,265. For example, 10 parsecs equal 2,062,650 astronomical units.
One astronomical unit equals 4.84814 × 10⁻⁶ parsecs.
2,475,180 astronomical units. Other common values: 5 parsecs = 1,031,320 astronomical units and 100 parsecs = 20,626,500 astronomical units.
