How to convert nautical miles to light years
1 nautical mile (international) is equal to 1.957565545 × 10⁻¹³ light years, and 1 light year is equal to 5,108,385,784,000 nautical miles. To convert, multiply by the conversion factor:
light years = nautical miles × 1.957565545 × 10⁻¹³
light years = nautical miles ÷ 5,108,385,784,000Example: convert 1 NM to ly: 1 × 1.957565545 × 10⁻¹³ = 1.957565545 × 10⁻¹³ ly.
