Welcome to our tutorial on Python programming where we will explore how to create a Python program to convert Fahrenheit to Celsius.
This is a common task in everyday life, especially if you’re dealing with temperature data or need to perform temperature conversions for various applications.
In this tutorial, we will walk through the process of creating a simple yet effective Python program that takes a temperature value in Fahrenheit as input and converts it into Celsius using a straightforward formula.
We will explain each step of the code in detail, making it easy for beginners to understand and follow along.
Introduction to Fahrenheit and Celsius
Before we dive into the programming aspect, let’s briefly understand the concepts of Fahrenheit and Celsius scales.
Fahrenheit (°F): The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the German physicist Daniel Gabriel Fahrenheit.
In this scale, the freezing point of water is 32 degrees Fahrenheit (°F), and the boiling point is 212°F.
Celsius (°C): The Celsius scale, also known as the centigrade scale, is a temperature scale used in most of the world.
In this scale, the freezing point of water is 0 degrees Celsius (°C), and the boiling point is 100°C.
Python Program to Convert Fahrenheit to Celsius
Let’s dive into the Python code to perform the conversion from Fahrenheit to Celsius.
Step 1: Taking Input from the User
The first step is to prompt the user to enter the temperature in Fahrenheit.
We will use the input() function to receive the input from the user and convert it to a floating-point number using the float() function.
# Python Program to Convert Fahrenheit to Celsius
# Prompting the user to enter the temperature in Fahrenheit
fahrenheit = float(input("Enter temperature in Fahrenheit: "))
We can use a simple formula to convert any given temperature from the Fahrenheit scale to the Celsius scale.
This formula is based on the relationship between Fahrenheit and Celsius temperatures.
Step 2: Conversion Formula
The formula to convert Fahrenheit to Celsius is:
celsius = (fahrenheit - 32) / 1.8
We subtract 32 from the Fahrenheit temperature and then divide the result by 1.8 to obtain the equivalent temperature in Celsius.
Step 3: Implementing the Conversion
Now, let’s implement the conversion formula in our Python program:
# Converting Fahrenheit to Celsius
celsius = (fahrenheit - 32) / 1.8
Here, we subtract 32 from the Fahrenheit temperature and then divide the result by 1.8 to get the temperature in Celsius.
Step 4: Displaying the Result
Finally, we will display the converted temperature in Celsius to the user. We use the print() function to output the result.
# Displaying the result
print("Temperature in Celsius:", celsius)
Complete Python Program to Convert Fahrenheit to Celsius
Putting all the code together, our complete Python program to convert Fahrenheit to Celsius looks like this:
# Python Program to Convert Fahrenheit to Celsius
# Prompting the user to enter the temperature in Fahrenheit
fahrenheit = float(input("Enter temperature in Fahrenheit: "))
# Converting Fahrenheit to Celsius
celsius = (fahrenheit - 32) / 1.8
# Displaying the result
print("Temperature in Celsius:", celsius)
That’s it! Our Python program successfully converts temperature from Fahrenheit to Celsius.
Example Usage
Let’s see how our Python program works with a few examples:
Example 1:
Suppose the user enters a temperature of 98.6 degrees Fahrenheit (normal body temperature).
The program will output the equivalent temperature in Celsius.
Enter temperature in Fahrenheit: 98.6
Temperature in Celsius: 37.0
Example 2:
Let’s convert freezing temperature, 32 degrees Fahrenheit, to Celsius:
Enter temperature in Fahrenheit: 32
Temperature in Celsius: 0.0
Conclusions: Python Program to Convert Fahrenheit to Celsius
In this tutorial, we learned how to create a simple Python program to convert Fahrenheit to Celsius.
We discussed the concepts of Fahrenheit and Celsius scales, the conversion formula, and implemented the conversion in Python code.
Python Program to Convert Fahrenheit to Celsius provides a practical example of using user input, mathematical operations, and output display in Python programming.
