undefined That's a great question! Let’s break it down step-by-step.

1. **What is a parsec?**  
   A parsec is a way to measure distance in space. It’s about 3.26 light years.

2. **What is a light year?**  
   A light year is how far light travels in one year. It’s very far!

3. **How do they compare?**  
   Since 1 parsec equals about 3.26 light years, we can say:  
   - 1 parsec = 3.26 light years

4. **Can you find both in a problem?**  
   Yes! If you know a distance in light years, you can change it to parsecs. For example, if something is 6.52 light years away, how many parsecs is that?

5. **How do you change light years to parsecs?**  
   You can divide the number of light years by 3.26.  
   So, 6.52 light years ÷ 3.26 = 2 parsecs.

6. **Why is this useful?**  
   It helps scientists talk about space distances better!

Does that help explain how parsecs and light years are related?
