C program to convert temperature from Fahrenheit to Celsius and Celsius to Fahrenheit.

In this example, we will see a C program through which we can convert the temperature value from Fahrenheit to Celsius and from Celsius to Fahrenheit.

Example :


/* C Program to convert temperature from Fahrenheit to Celsius and vice versa.*/
#include <stdio.h>
int main()
{
float fh,cl;
int choice;
printf("\n1: Convert temperature from Fahrenheit to Celsius."); 
printf("\n2: Convert temperature from Celsius to Fahrenheit.");
printf("\nEnter your choice (1, 2): ");
scanf("%d",&choice);
if(choice ==1){
printf("\nEnter temperature in Fahrenheit: ");
scanf("%f",&fh);
cl= (fh - 32) / 1.8;
printf("Temperature in Celsius: %.2f",cl);
}
else if(choice==2){
printf("\nEnter temperature in Celsius: ");
scanf("%f",&cl);
fh= (cl*1.8)+32;
printf("Temperature in Fahrenheit: %.2f",fh);
}
else{
printf("\nInvalid Choice !!!");
}
return 0;
}

Output:
1: Convert temperature from Fahrenheit to Celsius.
2: Convert temperature from Celsius to Fahrenheit.
Enter your choice (1, 2): 1
Enter temperature in Fahrenheit: 97.5
Temperature in Celsius: 36.39
