How to convert chains (US survey) to light years
1 chain (us survey) is equal to 2.12635169 × 10⁻¹⁵ light years, and 1 light year is equal to 470,289,089,300,000 chains (US survey). To convert, multiply by the conversion factor:
light years = chains (US survey) × 2.12635169 × 10⁻¹⁵
light years = chains (US survey) ÷ 470,289,089,300,000Example: convert 1 ch (US) to ly: 1 × 2.12635169 × 10⁻¹⁵ = 2.12635169 × 10⁻¹⁵ ly.

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.
