How to convert light years to nanometers
1 light year is equal to 9.460730473 × 10²⁴ nanometers, and 1 nanometer is equal to 1.057000834 × 10⁻²⁵ light years. To convert, multiply by the conversion factor:
nanometers = light years × 9.460730473 × 10²⁴
nanometers = light years ÷ 1.057000834 × 10⁻²⁵Example: convert 1 ly to nm: 1 × 9.460730473 × 10²⁴ = 9.460730473 × 10²⁴ nm.

About the light year
A light-year is the distance light travels in a vacuum in one Julian year (365.25 days): about 9.46 trillion km. The nearest star system, Alpha Centauri, is about 4.37 light-years away.
