  Users can convert between global currencies using real-time exchange rates. The source and target currencies can be selected from a predefined list, and the converted value is instantly displayed after the user submits the form.
• Live Exchange Rate Integration
  The application uses the open.er-api.com endpoint to fetch current currency values. This ensures the data is always up to date and reflects the latest exchange rates globally.
• Clean User Interface
  A simple HTML page built using Django’s templating system is used for input and output display. The interface supports form-based submission for selecting source and target currencies and entering the amount to convert.
