Python Weight Converter – Your Weight Conversion Genie

A weight converter is a programme that helps the user in converting one weighing unit to another. Here we will convert kg to ounces, pounds, and grams. A weight converter simplifies weight conversion by removing the need for calculation.

About Python Weight Converter

We will utilize the Tkinter Module to create this project. We will develop the GUI for our project using the Tkinter Module. We will create a graphical user interface window with an entry field for entering weight in kilograms and a button to convert it into pounds, grams, and ounces.

Prerequisites for Weight Converter using Python

• Basic knowledge of the Python programming language and how functions are defined in it.
• How the window is made in Tkinter GUI
• Basic formulas to convert weight into different units

Steps to Create Weight Converter using Python

Following are the steps for developing the Python Weight Converter Project:

Step 1: Importing the necessary modules

Step 2: Making a window for our project

Step 3: Functions

Step 4: Making Labels and Mapping the Button to its Functionality

Step 1: Importing the necessary modules

To use Tkinter, we need to import the Tkinter module.

Code

#import packages
from tkinter import *

Step 2: Making a window for our project

This code sets the title of the window as ‘ProjectGurukul’.

Code

converter = Tk()
converter.title("ProjectGurukul")
converter.resizable()

Step 3: Functions

This function converts the input weight which is in kg to pounds, grams, and ounces.

Code

# Function to convert given weight(kg) to- grams, pounds and ounces
def covert_to_kg():
   pound = float(value.get()) * 2.20462
   gram = float(value.get()) * 1000
   ounce = float(value.get()) * 35.274
   text1.delete("1.0", END)
   text1.insert(END, str(gram))


   text2.delete("1.0", END)
   text2.insert(END, str(pound))


   text3.delete("1.0", END)
   text3.insert(END, str(ounce))

Explanation:

We use value.get() to get the input weight, which is in kg, in float type and convert it to pounds, grams, and ounces and update their entries by text1.delete and text1.insert.

Step 4: Making Labels and Mapping the Button to its Functionality

Now we add the required widgets for our GUI. To display the values of kg, gram, pound, and ounce, we create four labels, an entry widget, and a text widget. We create a button widget and assign the covert_to_kg function to it.

Code

l0 = Label(converter, text="Enter Weight in Kg:")
l0.grid(row=0, column=0)
value = Entry(converter)
value.grid(row=0, column=1)
# creating the button widget
b = Button(converter, text="Convert", command=covert_to_kg)
b.grid(row=0, column=2)
# creating labels widget
l1 = Label(converter, text="Gram:")
l1.grid(row=1, column=0)
l2 = Label(converter, text="Pound:")
l2.grid(row=2, column=0)
l3 = Label(converter, text="Ounce:")
l3.grid(row=3, column=0)
# creating texts widget
text1 = Text(converter, width=10, height=1)
text1.grid(row=1, column=1)
text2 = Text(converter, width=10, height=1)
text2.grid(row=2, column=1)
text3 = Text(converter, width=10, height=1)
text3.grid(row=3, column=1)


converter.mainloop()

Python Weight Converter Output

Summary

The Weight Converter Project has been finished successfully. We learned how to create a GUI with the Tkinter Module and observed some fundamental Python principles. This project can be expanded by adding more conversions and items.
