How does the Conversion Work?
Step 1: Understand the base units
All length conversions go through meters (m).
- 1
Parsec =
30,856,775,814,913,672.000000 meter(s)
- 1
Light-year =
9,460,730,472,580,800.000000 meter(s)
Step 2: Set up the conversion factor
Conversion Factor = (From Unit Base) ÷ (To Unit Base)
=
30,856,775,814,913,672.000000 ÷
9,460,730,472,580,800.000000
=
3.261564
Step 3: Apply to your value
