§03Practical Example

Step-by-step walkthrough

Scenario

Convert 5 parsecs to astronomical units.

  1. 01Look up the SI factors: 1 parsec = 30856775814913670 base units, 1 astronomical unit = 149597870700 base units.
  2. 02Divide to get the conversion ratio: 30856775814913670 / 149597870700 = 206265.
  3. 03Multiply by the quantity: 5 × 206265 = 1031320.
  4. 04So 5 parsecs = 1031320 astronomical units.
