How does the Conversion Work?

Step 1: Understand the base units
All length conversions go through meters (m).
- 1 Light-year = 9,460,730,472,580,800.000000 meter(s)
- 1 Parsec = 30,856,775,814,913,672.000000 meter(s)

Step 2: Set up the conversion factor
Conversion Factor = (From Unit Base) ÷ (To Unit Base)
= 9,460,730,472,580,800.000000 ÷ 30,856,775,814,913,672.000000
= 0.306601

Step 3: Apply to your value
To convert Light-years to Parsecs:
Parsecs = Light-years × 0.306601

Example: Convert 1 Light-year to Parsecs
1 ly = 1 × 0.306601 pc
Result: 1 Light-year =
