Function or method of temperature conversion from Fahrenheit into Celsius
In this article, we will discuss the title of the “Function/method of temperature conversion from Fahrenheit into Celsius”.
In this post, we will learn how to write a program to convert Fahrenheit into Celsius (using the user input)Using the function 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 to Fahrenheit into Celsius.
Kelvin is an international unit in temperature measurement.
Formula
F=C x 9/5 + 32
Algorithm
- Declare variables as double
- initialize variable
- Define a user-defined function with a parameter
- Ask for input from the user
- Create an object and call the function using the object
- 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
//using method
import java.util.Scanner;
public class Fahrenheit_To_Celsius2
{//method definition
double fahre_tO_cels(double fahrenheit){
return ((fahrenheit-32)*5/9);
}
public static void main (String args[]){
//create object
Fahrenheit_To_Celsius2 res=new Fahrenheit_To_Celsius2();
//declaring variables
double fahre;
Scanner input=new Scanner(System.in);
System.out.print("Enter the value to Fahrenheit: ");
//Ask nput from the user
fahre=input.nextDouble();//Reading the value
double result=res.fahre_tO_cels(fahre);
//Calling the method
System.out.print("Temperature in Farhenheit:"+result);
//print the result
}
}
When the above code is executed, it produces the following result
Enter the value to Fahrenheit: 98.6 Temperature in Farhenheit:37.0
Convert Fahrenheit into Celsius – C
C language
Program 2
// C program to convert fahrenheit into celsius
//using function-Entered by user
#include <stdio.h>
//user deined function
float convertFahToCels(float fh){
// function definition
return ((fh-32)*5/9);
//Calcuate temperature in Celsius
}
int main() {
// declaring variables
float cels,fahr;
//ask input for variables
printf("Enter temparature in Fahrenheit :");
scanf("%f",&fahr);
//Convert fahrenheit into celsius
cels=convertFahToCels(fahr);
printf("The tempereture in Celsius is=%.2f ",cels);
return 0;
}
When the above code is executed, it produces the following result
Enter temperature in Fahrenheit:98.6 The temperature in Celsius is=37.00
Convert Fahrenheit into Celsius- C++
C++ language
Program 3
//C++ program to convert F into C using function
#include <iostream>
using namespace std;
float fahrenheitToCelsius(float);
//function prototype
int main() {
float fahrenheit;
//declare float type variables
// ask input from the user
cout<<"Enter the temperature in Fahrenheit:";
cin>>fahrenheit;//reading the input
//Calculate fahrenheit
float celsius=fahrenheitToCelsius(fahrenheit);
//Calling the function with argument
//display result on the screen
cout<<fahrenheit <<" Fahrenheit"<<" equal to "<<celsius<<" Celsius"<<endl;
return 0;
}//function definition
float fahrenheitToCelsius(float fahrenheit){
return ((fahrenheit-32) * 5/9);;
}
When the above code is executed, it produces the following result
Enter the temperature in Fahrenheit:60 60 Fahrenheit equal to 15.5556 Celsius
Convert Fahrenheit into Celsius – C#
C# language
Program 4
// C# program to convert Fahrenheit to Celsius
//using function
using System;
namespace Temperature
{
public class TempFahreToCels
{
public static void Main(string[] args)
{
Console.WriteLine ("Enter temperature in Fahrenheit: ");
//Ask input from the user
double Fahrenheit=Convert.ToDouble(Console.ReadLine());
//Reading the input
double celsius=FahrenheitTocelsius(Fahrenheit);
//Calling the function with argument
Console.WriteLine ("The temperature in Celsius: "+celsius);
//Dispay result on the screen
Console.ReadLine();
}
//function definition
private static double FahrenheitTocelsius(double fahrenheit)
{
return (((fahrenheit-32)*5)/9);
}
}
}
When the above code is executed, it produces the following result
Enter temperature in Fahrenheit: 212 The temperature in Celsius: 100
Convert Fahrenheit into Celsius- Python
Python language
Program 5
# Python program to convert temperature in Fahrenheit to Celsius
#using function
def convertFahreToCels(F):#user defined function
#Calculate temperature in Celsius
C=(F-32)/1.8
return C
fahrenheit=float(input("Enter temperature in Fahrenheit "))
#Ask input from the user
#Calling the finction
celsius=convertFahreToCels(fahrenheit)
#Display result
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 102.0 102.0 degrees Fahrenheit is equal to 38.9 degree Celsius
Convert Fahrenheit into Celsius- PHP
PHP language
Program 6
<?php
//PHP code to Convert Fahrenheit degrees to Celsius
//using function
function calc_Celsius(int $fahrenheit){
return ($fahrenheit-32) *5/9;
}//user define function to calculate fahrenheit
$fahrenheit=readline("Enter the Fahrenheit: ");
//Ask input from the user
echo("The temperature in Celsius is: ");
//$fahrenheit=round($celsius,3);
echo(calc_Celsius($fahrenheit));
//Display the output via calling the function
When the above code is executed, it produces the following result
Enter the Fahrenheit: 50.0 The temperature in Celsius is: 10
Convert Fahrenheit into Celsius- JavaScript
JavaScript language
Program 7
//Program to Convert Fahrenheit to Celsius
function fahreToCels(f){
return (fahrenheit-32)*5/9;
//function definition
}
const fahrenheit=prompt("Enter a Fahrenheit value: ");
//Take input from the user
var result=fahreToCels(fahrenheit)
//Calling the function
//Display the result
console.log(`${fahrenheit} degrees Fahrenheit is equal to ${result} degrees Celsius.` );
When the above code is executed, it produces the following result
Enter a Fahrenheit value: 212 212 degrees Fahrenheit is equal to 100 degrees Celsius.
