🧮 Formula

Chains to Light Years
ly = ch × 2.12635 × 10⁻¹⁵
Light Years to Chains
ch = ly × 470,290,029,854,689

Where

  • ch = the length in chains
  • ly = the length in light years
Every unit here is defined by its length in meters, so the conversion factor is (meters per chain) ÷ (meters per light year).
