How it’s calculated

1 astronomical unit = 4.84814e-6 parsecs → value_in_parsec = value_in_astronomical_unit × 4.84814e-6

Where

value_in_astronomical_unit
The number of astronomical units you start with (the value you enter above)
value_in_parsec
The equivalent number of parsecs (the result)
factor
The exact conversion ratio — 4.84814e-6 — anchored to SI definitions, not rounded
§03Practical Example

Step-by-step walkthrough

Scenario

Convert 5 astronomical units to parsecs.

  1. 01Look up the SI factors: 1 astronomical unit = 149597870700 base units, 1 parsec = 30856775814913670 base units.
  2. 02Divide to get the conversion ratio: 149597870700 / 30856775814913670 = 4.84814e-6.
  3. 03Multiply by the quantity: 5 × 4.84814e-6 = 2.42407e-5.
  4. 04So 5 astronomical units = 2.42407e-5 parsecs.
