Python PyQt Convert Kilograms To Pounds

Python PyQt Convert Kilograms To Pounds – To create a PyQt GUI program that converts kgs to lbs, you can use a similar approach as in the previous examples.

Here’s a basic PyQt program to perform this conversion:

Source Code

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QLabel, QLineEdit, QPushButton

class KilogramsToPoundsConverter(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        self.setWindowTitle('Kilograms to Pounds Converter')
        self.setGeometry(100, 100, 300, 150)

        # Create a vertical layout
        layout = QVBoxLayout()

        # Create input field for kilograms
        self.kilograms_label = QLabel('Enter kilograms:')
        self.kilograms_input = QLineEdit()

        # Create a label to display the result
        self.result_label = QLabel('Pounds:')

        # Create a button to perform the conversion
        self.convert_button = QPushButton('Convert')

        # Connect the button click event to the conversion function
        self.convert_button.clicked.connect(self.performConversion)

        # Add widgets to the layout
        layout.addWidget(self.kilograms_label)
        layout.addWidget(self.kilograms_input)
        layout.addWidget(self.convert_button)
        layout.addWidget(self.result_label)

        # Set the layout for the main window
        self.setLayout(layout)

    def performConversion(self):
        try:
            # Get the kilograms value from the input field
            kilograms = float(self.kilograms_input.text())

            # Perform the conversion: 1 kilogram = 2.20462 pounds
            pounds = kilograms * 2.20462

            # Display the result
            self.result_label.setText(f'Pounds: {pounds:.2f}')
        except ValueError:
            # Handle invalid input (e.g., non-numeric input)
            self.result_label.setText('Invalid input')

def main():
    app = QApplication(sys.argv)
    window = KilogramsToPoundsConverter()
    window.show()
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

This code creates a PyQt application with a window containing an input field for the user to enter kilograms, a button to perform the conversion, and a label to display the result in pounds. When the user enters a value in kilograms and clicks the “Convert” button, the conversion is performed and displayed in the label.

Make sure you have PyQt5 installed (pip install PyQt5) before running this code.
