Question

How to convert fahrenheit to celsius in C

Answer 1

#include <stdio.h> 

float FahrenheitToCelsius(float f);

int main(int argc, char **argv) 
{
    float temp_f, temp_c;

    printf("Enter Temperature in Fahrenheit: ");
    scanf("%f", &temp_f);
    temp_c = FahrenheitToCelsius(temp_f);
    printf("%.2f Fahrenheit = %.2f celsius\n",temp_f, temp_c);

    return(0);
}
float FahrenheitToCelsius(float f)
{
    float t;
    
    t = (f - 32) / 1.8;
    
    return(t);
}


/*
run1:

Enter Temperature in Fahrenheit: 1
1.00 Fahrenheit = -17.22 celsius

run2:

Enter Temperature in Fahrenheit: 50
50.00 Fahrenheit = 10.00 celsius

Answer 3

#include <stdio.h>
  
int main(void) {
    int fahrenheit = 96;
      
    double celsius = (fahrenheit - 32) * 5 / 9.0;
      
    printf("Celsius = %f", celsius);
}
  
  
  
  
/*
run:
    
Celsius = 35.555556
