C Program 6: To convert the temperature from Fahrenheit to Celsius.

Aim: Temperature of a city in Fahrenheit degree is input through the keyboard. Write a program to convert this temperature into Centigrade degrees.

Theory: This is one of the basic programs that one should know to make in the C but the only tough part is remembering the formula for conversion of temperature from one scale to another. There is no logic in that. It's just a mathematical formula which you need to keep in mind. The Formula is C= 5(F+32)/9

Code:

//to convert temperature from Fahrenheit to Celsius

#include<stdio.h>

#include<conio.h>

int main()

{

    float fahf, celf;

    printf("Enter the temperature in Fahrenheit: ", fahf);

    scanf("%f", &fahf);

    celf=5*(fahf-32)/9;

    printf("The temperature in Celsius is: %f", celf);

    getch();

    return 0;

}

We just took two variables and then used the formula which I mentioned above in the theory portion. Here's the output:
