Python Program to convert Fahrenheit to Celsius

Python Program - Convert Fahrenheit to Celsius

To convert Fahrenheit to Celsius, you can use the following formula in the program.

Celsius = (Fahrenheit - 32) * 5 / 9

Let us write a function, that takes the Fahrenheit value as argument, computes the Celsius using the above formula, and return the result.

def fahrenheitToCelsius(f):
    return (f - 32) * 5 / 9

You may use this function, in your program, to convert Fahrenheit to Celsius.

The following is an example program, where we shall use the above conversion function, and convert 98.6 Fahrenheit to Celsius and print the result to output.

Python Program

# Function that converts F to C
def fahrenheitToCelsius(f):
    return (f - 32) * 5 / 9

if __name__ == "__main__":
    # Given Fahrenheit
    f = 98.6

    # Convert Fahrenheit to Celsius
    c = fahrenheitToCelsius(f)

    print(f"{f} Fahrenheit is equal to {c} Celsius")

Output

98.6 Fahrenheit is equal to 37.0 Celsius

To implement the formula, we used Python Subtraction, Python Multiplication, and Python Division from Python Arithmetic Operators.
