Temperature Converter

Goals

• Define functions with parameters and return values
• Apply the temperature conversion formulas correctly
• Format output with f-strings
• Read and convert user input

Prerequisites

• Functions and return values
• Basic arithmetic
• input() and float()

Steps

2. 1

   Write the conversion functions

   Define celsius_to_fahrenheit(c) and fahrenheit_to_celsius(f). The formulas are F = C * 9/5 + 32 and C = (F - 32) * 5/9. Each function takes one number and returns one number.

   CodeCopy

   def celsius_to_fahrenheit(c):
       return c * 9 / 5 + 32
   
   def fahrenheit_to_celsius(f):
       return (f - 32) * 5 / 9

   Expected result

   celsius_to_fahrenheit(0) returns 32.0; fahrenheit_to_celsius(98.6) returns about 37.0.

4. 2

   Read input from the user

   Ask the user for a temperature in Celsius and convert the input string to a float. float() handles decimal input like 36.6.

   CodeCopy

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

   Expected result

   The script waits for input and stores the numeric value in c.

6. 3

   Print the result with an f-string

   Call the conversion function and print the result using an f-string. f-strings let you embed expressions directly inside the string with curly braces.

   CodeCopy

   f = celsius_to_fahrenheit(c)
   print(f"{c}°C = {f}°F")

   Expected result

   Typing 25 prints "25.0°C = 77.0°F".
