+# SGPA to CGPA Converter
+
+This is a simple GUI application built using Python and Tkinter that converts SGPA (Semester Grade Point Average) to CGPA (Cumulative Grade Point Average) based on user inputs.
+
+## Features
+
+- Allows users to enter the total number of semesters and their corresponding SGPA values.
+- Calculates the CGPA based on the entered SGPA values.
+- Supports resetting the inputs and results for a fresh calculation.
+
+## Requirements
+
+- Python 3.x
+- Tkinter library (usually included with Python)
+
+## How to Use
+
+1. Install Python 3.x if it's not already installed on your system.
+2. Clone or download this repository to your local machine.
+3. Open a terminal or command prompt and navigate to the project directory.
+4. Run the following command to install the required dependencies:
+    ```
+    pip install tkinter
+    ```
+5. Run the application using the following command:
+    ```
+    python sgpa_to_cgpa_converter.py
+    ```
+6. Enter the total number of semesters and the corresponding SGPA values.
+7. Click the "Calculate CGPA" button to compute the CGPA based on the entered values.
+8. To reset the inputs and results, click the "Reset" button.
