There are approximately 4.23 cups in 1 liter.

Explanation:

• 1 liter = 1000 milliliters (ml)
• 1 US cup = 236.588 ml
• So, 1000 ml ÷ 236.588 ml ≈ 4.23 cups

If you are using a different cup measurement (like the UK cup), the value will vary slightly. Let me know if you want conversions for other cup sizes!
