Attention reader! All those who say programming isn't for kids, just haven't met the right mentors yet. Join the  Demo Class for First Step to Coding Coursespecifically designed for students of class 8 to 12. 

The students will get to learn more about the world of programming in these free classes which will definitely help them in making a wise career choice in the future.

Formula for converting Fahrenheit scale to Celsius scale 
 



T(°C) = (T(°F) - 32) × 5/9

 

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));
}
}

Python3




# Python3 program to convert Fahrenheit
# scale to Celsius scale
 
# function to convert
# Fahrenheit to Celsius
def Conversion(n):
    return(n - 32.0) * 5.0 / 9.0
 
# driver code
n = 40
x = Conversion(n)
print (x)

<?php
// PHP program to convert Fahrenheit
// scale to Celsius scale
 
// function to convert
// Fahrenheit to Celsius
function Conversion($n)
{
    return ($n - 32.0) * 5.0 / 9.0;
}
 
    // Driver Code
    $n = 40;
    echo Conversion($n);
