Program for Fahrenheit to Celsius conversion

Last Updated : 26 Feb, 2021

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++

// 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));
}
}
