Fahrenheit to Celsius Converter

How does it work?

Generally to measure the temperature we make use of one of these two popular units i.e. Fahrenheit & Celsius.

Converting one into another is usually boring and can be easily automated. Today we will be building a simple & short project which will convert Fahrenheit to Celsius for us in seconds.

Let's Code

So the first thing we are going to do is to ask the user for the temperature in Fahrenheit to convert it into the Celsius.

temp = input("Enter temperature in Fahrenheit: ")

We will convert the temperature into float using float() so that we can perform calculations on it.

temp = float(temp)

Now finally let's perform calculation and convert the temperature into Celsius.

celsius = (temp - 32) * 5/9

This expression you see above is the general formula to convert Fahrenheit into Celsius.

Now finally let's print our temperature in Celsius:

print(f"{temp} in Fahrenheit is equal to {celsius} in Celsius")

Here we go we are done! Here we have used f-strings to directly place the variable within the print statement.

Putting all together in a function:

def fahrenheit_to_celsius():
    temp = input("Enter temperature in Fahrenheit: ")
    temp = float(temp)
    celsius = (temp - 32) * 5/9
    print(f"{temp} in Fahrenheit is equal to {celsius} in Celsius")

Let's try:

>>> fahrenheit_to_celsius()
Enter temperature in Fahrenheit: 32
32.0 in Fahrenheit is equal to 0.0 in Celsius

Perfect!
