C program to convert Temperature from Fahrenheit to Celsius and Celsius to Fahrenheit - My CS Tutorial

C program to convert Temperature from degree Celsius to Fahrenheit and Fahrenheit to Celsius.

In this program we will learn how to write a c program that convert Temperature from Fahrenheit to Celsius and Celsius to Fahrenheit.

Program Description:

Here we will write a c program that solve both operations as Fahrenheit to Celsius and Celsius to Fahrenheit.
This program provides a choice to user that which operation will be execute.

In this program choice1 is: ENTER 1 FOR CONVERT FAHRENHEIT TO CELSIUS.
And choice2 is: ENTER 2 FOR CONVERT CELSIUS TO FAHRENHEIT."

To make a C program to convert Temperature from Fahrenheit to Celsius and Celsius to Fahrenheit we will use simple mathematical formulas which are as:


Formula for Fahrenheit to Celsius conversion:-


Celsius=((Fahrenheit-32)*(5/9.0))


Formula for Celsius to Fahrenheit conversion:-


Fahrenheit=(Celsius*1.8)+32

C program code

#include<stdio.h>

#include<conio.h>

void main()

{

float c,f;

int choice;

clrscr();

printf("\n ENTER 1 FOR CONVERT FAHRENHEIT TO CELSIUS.");

 printf("\n ENTER 2 FOR CONVERT CELSIUS TO FAHRENHEIT.");

 printf("\n");

 printf("\n ENTER YOUR CHOICE:\n ");

 scanf("%d",&choice);

 switch(choice)

 {

  case 1:

             printf("\n ENTER THE VALUE OF FAHRENHEIT:\n " );

             scanf("%f",&f);

             c=((f-32)*(5/9.0));

             printf("\n THE VALUE OF CELSIUS:\n %f",c);

             break;

             

  case 2:

             printf("\n ENTER THE VALUE OF CELSIUS:\n " );

             scanf("%f",&c);

             f=(c*1.8)+32;

             printf("\n THE VALUE OF FAHRENHEIT:\n %f",f);

             break;  

             

      default:

                   printf("\n WRONG ENTRY.");

                   }

                   

getch();

}

OUTPUT:

In this output we can see that it is a Temperature converter.
This program provides a choice to user that which operation will be execute.
if we will enter 1 then it converts Temperature from Fahrenheit to Celsius if we will enter 2 then it converts Celsius to Fahrenheit .

If we will enter any other number from 1 or 2 then it is print WRONG ENTRY.
