How to convert light years to X-units
1 light year is equal to 9.441092999 × 10²⁸ X-units, and 1 x-unit is equal to 1.059199396 × 10⁻²⁹ light years. To convert, multiply by the conversion factor:
X-units = light years × 9.441092999 × 10²⁸
X-units = light years ÷ 1.059199396 × 10⁻²⁹Example: convert 1 ly to xu: 1 × 9.441092999 × 10²⁸ = 9.441092999 × 10²⁸ xu.
