+# 🌡️ Temperature Converter
+
+A simple and interactive Python program to convert temperatures between **Celsius**, **Fahrenheit**, and **Kelvin**.
+
+## 🚀 Features
+- Convert between all major temperature units  
+- Clean and easy-to-use CLI interface  
+- Accurate conversion formulas  
+
+## 🧩 How to Run
+```bash
+python temperature_converter.py
+```
+
+## 📖 Example
+```
+🌡️ Temperature Converter
+1. Celsius to Fahrenheit
+2. Fahrenheit to Celsius
+3. Celsius to Kelvin
+4. Kelvin to Celsius
+5. Fahrenheit to Kelvin
+6. Kelvin to Fahrenheit
+Enter choice (1–6): 1
+Enter Celsius: 25
+25°C = 77.00°F
+```
