Write temperature conversion program: from Fahrenheit to Celsius
In this article, we will discuss the title of the “Write temperature conversion programs from Fahrenheit to Celsius”
In this post, we will learn how to write a program to convert Fahrenheit into Celsius (Using the user input ) and display the result on the screen.
Generally, we are using three temperature units Fahrenheit, Celsius, and Kelvin. Fahrenheit and Celsius are the measuring units in degrees as oF and oC respectively. In this article, we are discussing how to convert temperature units Fahrenheit into Celsius.
Kevin is an international unit in temperature measurement.
Formula
F=C x 9/5 + 32
Algorithm
- Declare variables as double
- Ask for input from the user
- Apply the formula and calculate Celsius
- Print the temperature in Celsius on the screen
Code to Fahrenheit into Celsius
Convert Fahrenheit into Celsius – Java
Java language
Program 1
//Java program to Convert Fahrenheit into Celsius
import java.util.Scanner;
public class Fahrenheit_To_Celsius
{
public static void main (String args[]){
//declaring variables
double fahre,cels;
Scanner input=new Scanner(System.in);
System.out.print("Enter the value to Fahrenheit: ");
//Ask input rom the user
fahre=input.nextDouble();
//Reading the input
cels=(((fahre-32)*5)/9);
//Calculate Celsius value
System.out.print("Temperature in Celsius:"+cels);
//print the result on the screen
}
}
When the above code is executed, it produces the following result
Enter the value to Fahrenheit: 104 Temperature in Celsius:40.0
Convert Fahrenheit into Celsius – C
C language
Program 2
// C program to convert Temparature
// fahrenheit into celsius
#include <stdio.h>
int main() {
//variable declaration
float celsius,fahrenheit;
//asking input from user
printf("Enter the temperature in Fahrenheit :");
scanf("%f",&fahrenheit);
//Reading the input from the user
//Convert fahrenheit into celsius
celsius=((fahrenheit-32)*5/9);
//Calculate Celsius value
printf("The temperature in Celsius is=%.2f ",celsius);
return 0;
}
When the above code is executed, it produces the following result
Enter the temperature in Fahrenheit:70 The temperature in Celsius is=21.11
Convert Fahrenheit into Celsius – C++
C++ language
Program 3
//C++ program to convert F into C
//Taking input
#include <iostream>
using namespace std;
int main() {
float celsius, fehrenheit;
//declaration of float type variables
cout<<"Enter the temparature in fehrenheit:";
// ask input from the user
cin>>fehrenheit;//reading the input
//Calculate Celsius
celsius=((fehrenheit-32) * 5/9);
cout<<fehrenheit<<" Fehrenheit is: "<<celsius <<" Celsius";
//display result on the screen
return 0;
}
When the above code is executed, it produces the following result
Enter the temparature in fehrenheit:200 200 Fehrenheit is: 93.3333 Celsius
Convert Fahrenheit into Celsius – C#
C# language
Program 3
// C# program to convert Fahrenheit to Celsius
//Take input rom the user
using System;
namespace temperature
{
public class FtoC
{
public static void Main(string[] args)
{
double celsius,fahrenheit;
//variable Declaration
Console.WriteLine ("Enter temperature in Fahrenheit: ");
//Ask input from user for fahrenheit
fahrenheit=Convert.ToDouble(Console.ReadLine());
//Reading the input
celsius=((fahrenheit-32)*5/9);
//Caculate Celsius
Console.WriteLine ("The temperature in Celsius: "+celsius);
//print celsius
Console.ReadKey();
}
}
}
When the above code is executed, it produces the following result
Enter temperature in Fahrenheit: 50.0 The temperature in Celsius: 10
Convert Fahrenheit into Celsius – Python
Python language
Program 5
# Python program to convert temperature in Fahrenheit to Celsius
fahrenheit=float(input("Enter temperature in Fahrenheit "))
#Ask input from the user
#Calculate celsius value
celsius=((fahrenheit-32)*5)/9
#Display result on the screen
print('%0.1f degrees Fahrenheit is equal to %0.1f degree Celsius' %(fahrenheit,celsius))
When the above code is executed, it produces the following result
Enter temperature in Fahrenheit 70.0 70.0 degrees Fahrenheit is equal to 21.1 degree Celsius
Convert Fahrenheit into Celsius – PHP
PHP language
Program 6
<?php
//PHP code to Convert to Fahrenheit into Celsius degrees
$fahrenheit=readline("Enter the Fahrenheit value: ");
//Takes input from user
$celsius=(($fahrenheit-32)*5)/9;
//Calculate celsius
echo("The temperature in Celsius is: ");
$celsius=round($celsius,3);
echo(($celsius));
//Print the result
?>
When the above code is executed, it produces the following result
Enter the Fahrenheit value: 190 The temperature in Celsius is: 87.778
Convert Fahrenheit into Celsius – Javascript
Javascript language
Program 7
//program to Convert Fahrenheit to Celsius
//Take input from the user
const fahrenheit=prompt("Enter a Fahrenheit value: ");
const celsius=(fahrenheit-32)*5/9;
//Calculate temperature of Celsius
console.log(`${fahrenheit} degrees Fahrenheit is equal to ${celsius} degrees Celsius.` );
//Display the result on the screen
When the above code is executed, it produces the following result
Enter a Fahrenheit value: 200.0 200.0 degrees Fahrenheit is equal to 93.33 degrees Celsius.
