    How to convert Fahrenheit to Celsius?

    How do I write a program that converts asks the user to enter a temperature in Fahrenheit, reads the
    entered value, converts it to Celsius using the formula and prints the value to
    the console?

    Needs to use this: T C=(T F−32)⋅5/9

    Re: How to convert Fahrenheit to Celsius?

    use cin >> to obtain the temperature in Fahrenheight (say f as type double), then use cout << to display the converted value

    Code:
    double f;
    cin >> f;
    cout << (f - 32.0) * 5.0 / 9.0 << endl;
    Is this a homework assignment?

    Have a look at http://forums.codeguru.com/showthrea...ork-assignment so you can get an idea as to the amount of help we'll be able to provide for homework type questions.

    If you are taking a c++ course and have had these exercises set as homework, I don't understand how these could be considered 'hardest problems' as they are quite trivial. What has your instructor covered and what book has been suggested?

    Have you actually written yet a c++ program that compiled correctly and was able to be executed OK? if so for what?

    Please don't ask homework assignments until you have done enough progress which is satisfactory.
    Though you can do it like this:

    Code:
    Code:
    #include<iostream>
    using namespace std;
    
    int main ()
    {
        double f;
        double c;
    
        cout <<"Enter the Farenheit value" << endl;
        cin >> f;
    
        c=(f-32)*5/9;
        cout << " The Celsius value is:"<< c << endl;
    
        return 0;
    }
