Python | Tkinter GUI to Convert Temperature from Celsius to Fahrenheit

In this tutorial let’s write Python Script to design Tkinter GUI to Convert Temperature from Celsius to Fahrenheit Desktop App

Python Code to create Tkinter GUI to Convert Temperature from Celsius to Fahrenheit

app.py : You can save the below code with app.py filename.

import tkinter as Tkinter

temp_c = None
temp_f = None

def convert():

    global temp_c
    global temp_f

    try:
        val = temp_c.get()
        temp_f.set((val * 9.0 / 5) + 32)
    except:
        pass

# main window
window = Tkinter.Tk()
window.title("Temperature Converter")


frame = Tkinter.Frame(window)

frame.pack(fill=Tkinter.BOTH, expand=True)
frame.columnconfigure(1, weight=1)
frame.rowconfigure(1, weight=1)

temp_c = Tkinter.DoubleVar()
temp_f = Tkinter.DoubleVar()

# create widgets
entry_celsius = Tkinter.Entry(frame, width=7, textvariable=temp_c)
label_unitc = Tkinter.Label(frame, text="degrees C")
label_equal = Tkinter.Label(frame, text="is equal to")
label_fahrenheit = Tkinter.Label(frame, textvariable=temp_f)
label_unitf = Tkinter.Label(frame, text="degrees F")
button_convert = Tkinter.Button(frame, text="Convert", command=convert)


entry_celsius.grid(row=0, column=1, padx=5, pady=5)
label_unitc.grid(row=0, column=2, padx=5, pady=5, sticky=Tkinter.W)
label_equal.grid(row=1, column=0, padx=5, pady=5, sticky=Tkinter.E)
label_fahrenheit.grid(row=1, column=1, padx=5, pady=5)
label_unitf.grid(row=1, column=2, padx=5, pady=5, sticky=Tkinter.W)
button_convert.grid(row=2, column=1, columnspan=2, padx=5, pady=5, sticky=Tkinter.E)

entry_celsius.focus()


window.mainloop()

Output:

To execute the code through command line, you can use python3 app.py
