↔ Convert decimeters to light years instead

🧮 Formula

Light Years to Decimeters
dm = ly × 9.46073 × 10¹⁶
Decimeters to Light Years
ly = dm × 1.057 × 10⁻¹⁷

Where

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