To convert astronomical units to parsecs, multiply the value by 4.84814 × 10⁻⁶. To go the other way, multiply parsecs by 206,265 to get astronomical units.
| Astronomical Units (AU) | Parsecs (pc) |
|---|---|
| 1 AU | 4.84814 × 10⁻⁶ pc |
| 5 AU | 2.42407 × 10⁻⁵ pc |
| 10 AU | 4.84814 × 10⁻⁵ pc |
| 25 AU | 0.000121203 pc |
| 50 AU | 0.000242407 pc |
| 100 AU | 0.000484814 pc |
| 250 AU | 0.00121203 pc |
| 500 AU | 0.00242407 pc |
| 1,000 AU | 0.00484814 pc |
| 2,500 AU | 0.0121203 pc |
| 5,000 AU | 0.0242407 pc |
| 10,000 AU | 0.0484814 pc |
| 100,000 AU | 0.484814 pc |
| 1,000,000 AU | 4.84814 pc |
250 AU × 4.84814 × 10⁻⁶ = 0.00121203 pc
Try this example →Astronomical unit (AU). An astronomical unit is the average distance from the Earth to the Sun, about 149.6 million kilometers.
Parsec (pc). A parsec is about 3.26 light years and is used by astronomers for distances between stars.
There are 4.84814 × 10⁻⁶ parsecs in one astronomical unit.
Multiply the number of astronomical units by 4.84814 × 10⁻⁶. For example, 10 astronomical units equal 4.84814 × 10⁻⁵ parsecs.
One parsec equals 206,265 astronomical units.
0.00484814 parsecs. Other common values: 100 astronomical units = 0.000484814 parsecs and 10,000 astronomical units = 0.0484814 parsecs.
