Interactive Temperature Converter with Celsius, Fahrenheit, and Kelvin

[MohdFuzailHaider]

Summary

This PR enhances the original temperature converter by adding an interactive multi-scale conversion tool.

Changes Made

• Added options to convert Celsius, Fahrenheit, and Kelvin in both directions.
• Added looping, so users can convert multiple times without restarting the program.
• Added exit option to quit the program gracefully.
• Rounded conversion results to 2 decimal places.
• Improved user interface and messages for better clarity.

Example Run

---

Choose a scale to convert from:

1. Celsius

3. Kelvin
4. Exit
   Enter 1, 2, 3 or 4: 1
   Enter temperature: 25
5. Convert to Fahrenheit
6. Convert to Kelvin
   Enter 1 or 2: 1
   25°C = 77.0°F
   Press Enter to continue...

Good progress 👍 — multi-scale conversion + loop works well.
For next upgrade, please:

1. Refactor into functions (cleaner, testable code).
2. Add requirements.txt and proper README.md.
3. Make project production-ready (clear structure, docs).
4. Start a Tkinter GUI version with dropdowns, input field, and result display.

Thanks a lot for the review and kind feedback 🙌
I’ll work on refactoring the code into functions, adding requirements.txt and a README.md for better documentation.
The idea of making it production-ready and starting a Tkinter GUI version sounds great — I’ll begin implementing those improvements and push the updates soon.
