1 Parsec = 206168.850 AU.

Explanation:

1 Parsec = 3.26 light years.

1 Light Year = 9.4 trillion km. or 9.4 x 10^12 km

1 Astronomical Unit is 149 million km or 1.49 x 10^8 km

so there are 9.4 X 10^12/ 1.49 X 10^8 AU in 1 light year

there are, 63241.97 AU in 1 Light year

1 Parsec = 63241.97 * 3.26

1 Parsec = 206168.850 AU.
