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