Convert Au to Ly (Length)




Description:

One astronomical unit equals about 1.5813×10⁻⁵ light‑years. This means the Earth–Sun distance is only a tiny fraction of a light‑year, useful for scaling solar‑system distances into interstellar terms.
General Formula: \[(au \times 1.5813\times10^{-5}) = ly\]
Symbols: au (astronomical unit) ≈ 149.6 million km; ly (light‑year) = distance light travels in one year; 1.5813×10⁻⁵ = number of light‑years in one astronomical unit.
