Day 40: Python Program to Convert Celsius to Fahrenheit

 def celsius_to_fahrenheit(celsius):

    fahrenheit = (celsius * 9/5) + 32

    return fahrenheit

celsius = float(input("Enter temperature in Celsius: "))

fahrenheit = celsius_to_fahrenheit(celsius)

print(f"{celsius}°C is equal to {fahrenheit}°F")

Code Explanation:

1. Function Definition

def celsius_to_fahrenheit(celsius):

    fahrenheit = (celsius * 9/5) + 32

    return fahrenheit

def keyword: Used to define a function in Python.

celsius_to_fahrenheit: The name of the function that describes its purpose (convert Celsius to Fahrenheit).

celsius: A parameter passed to the function, representing the temperature in Celsius.

Formula:

Fahrenheit =(Celsius×9/5)+32

Multiply the Celsius value by 9/5 to convert it to Fahrenheit scale.

Add 32 because 0°𝐶 equals 32°𝐹.

return fahrenheit: The function returns the calculated Fahrenheit value.

2. User Input

celsius = float(input("Enter temperature in Celsius: "))

input(): Takes input from the user as a string.

float(): Converts the input string to a floating-point number so calculations can be performed.

"Enter temperature in Celsius: ": A message displayed to the user prompting them to input a value.

Example Input:

Enter temperature in Celsius: 25

Here, 25 will be converted to 25.0 as a float.

3. Function Call

fahrenheit = celsius_to_fahrenheit(celsius)

The celsius_to_fahrenheit() function is called with the user-provided Celsius value.

The returned Fahrenheit value is stored in the variable fahrenheit.

Example Calculation:

If the user enters 25, the calculation will be:

Fahrenheit =(25×9/5)+32=77.0

4. Output

print(f"{celsius}°C is equal to {fahrenheit}°F")

f-string: A formatted string used to print the values of variables within a string.

{celsius}: Inserts the Celsius value entered by the user.

{fahrenheit}: Inserts the calculated Fahrenheit value.

Example Output:

25.0°C is equal to 77.0°F
