Given a Temperature n in Fahrenheit scale convert it into Celsius scale .
Examples: 
 

Input : 32
Output : 0

Input :- 40
Output : -40

 

Formula for converting Fahrenheit scale to Celsius scale 
 

T(°C) = (T(°F) - 32) × 5/9

 

C




/* Program in C to convert Degree Fahrenheit to Degree Celsuis */
#include <stdio.h>
 
//function to convert Degree Fahrenheit to Degree Celsuis
float fahrenheit_to_celsius(float f)
{
  return ((f - 32.0) * 5.0 / 9.0);
}
 
int main()
{
 
  float f = 40;
 
  // passing parameter to function
  printf("Temperature in Degree Celsius : %0.2f",fahrenheit_to_celsius(f));
  return 0;
}

C++




// CPP program to convert Fahrenheit
// scale  to Celsius scale
#include <bits/stdc++.h>
using namespace std;
 
// function to convert
// Fahrenheit to Celsius
float Conversion(float n)
{
    return (n - 32.0) * 5.0 / 9.0;
}
 
// driver code
int main()
{
    float n = 40;
    cout << Conversion(n);
    return 0;
}

Java




// Java program to convert Fahrenheit
// scale to Celsius scale
class GFG {
     
// function to convert
// Fahrenheit to Celsius
static float Conversion(float n)
{
    return (n - 32.0f) * 5.0f / 9.0f;
}
 
// Driver code
public static void main(String[] args) {
    float n = 40;
    System.out.println(Conversion(n));
}
}
