Program

# Python Program to convert temperature in fahrenheit to celsius
fahrenheitVal = float(input('Enter a Fahrenheit value you want to convert: '))
# calculate celsius using the formula
# celsius * 1.8 = fahrenheit - 32
celsius = (fahrenheitVal - 32)/1.8
print('%0.1f degree Fahrenheit = %0.1f degree celsius' %(fahrenheitVal,celsius))

This program converts a temperature in Fahrenheit to Celsius using a simple mathematical formula.

1. Take User Input

   • The user enters a temperature in Fahrenheit as a floating-point number.

2. Convert to Celsius

   • The program applies the formula:
     [
     \text{Celsius} = \frac{(\text{Fahrenheit} - 32)}{1.8} ]
   • This formula converts Fahrenheit to Celsius.

3. Display Output

   • The result is printed with one decimal place using '%0.1f'.

Key Takeaways

• The formula (F - 32) / 1.8 is used for conversion.
• The program supports decimal values as input.
• The output is formatted to one decimal place for better readability.
