How many AU is one light year? (ChatGPT, 2025-5-30) (自體的心理學)(車行哲學)

 One light year is approximately 63,241 astronomical units (AU).



Here’s the breakdown:



  • 1 light year = the distance light travels in one year
    ≈ 9.4607 × 10¹² kilometers
  • 1 astronomical unit (AU) = average distance from the Earth to the Sun
    ≈ 1.496 × 10⁸ kilometers




Calculation:



\frac{9.4607 \times 10^{12} \text{ km}}{1.496 \times 10^8 \text{ km/AU}} \approx 63,241 \text{ AU}


Let me know if you’d like a visual scale comparison or a table for distances in AU vs. light years.
