How does the Conversion Work?

Step 1: Understand the base units
All length conversions go through meters (m).
- 1 Astronomical Unit = 149,597,870,700.000000 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)
= 149,597,870,700.000000 ÷ 9,460,730,472,580,800.000000
= 0.000016

Step 3: Apply to your value
To convert Astronomical Units to Light-years:
Light-years = Astronomical Units × 0.000016

Example: Convert 1 Astronomical Unit to Light-years
1 au = 1 × 0.000016 ly
Result: 1 Astronomical Unit =
