Welcome folks today in this blog post we will be building a distance converter km to miles gui desktop app in tkinter using python. All the full source code of the application is given below.

Get Started

In order to get started you need to make an app.py file and copy paste the following code

app.py

import tkinter

window = tkinter.Tk()
window.title("Mile To Km Converter")
window.minsize(width=400, height=200)
window.config(padx=80, pady=50)

label1 = tkinter.Label(text="Miles")
label1.grid(column=2, row=0)

label2 = tkinter.Label(text="is equal to")
label2.grid(column=0, row=1)

label3 = tkinter.Label(text="Km")
label3.grid(column=2, row=1)

label4 = tkinter.Label(text=0)
label4.grid(column=1, row=1)


def calc():
    miles = int(entry.get())
    km = round(miles * 1.609)
    label4.config(text=f"{km}")


button = tkinter.Button(text="Calculate", command=calc)
button.grid(column=1, row=2)


entry = tkinter.Entry()
entry.grid(column=1, row=0)


window.mainloop()

Now if you execute the python script by typing the below command as shown below

python app.py
