Using Function or Method to Write to temperature conversion: Fahrenheit into Celsius
In this article, we will discuss the title “Using Function or Method to Write temperature conversion: Fahrenheit into Celsius”.
In this post, we will learn how to write a program to convert Fahrenheit into Celsius 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 Fahrenheit into Celsius.
Kevin is an international unit in temperature measurement
Formula
F=C x 9/5 + 32
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_Celsius
{
static double cels_tO_fahre(double Fahrenheit){
return ((Fahrenheit-32)*5/9);
//Calculate celsius value
//and return the result to main method
}
public static void main (String args[]){
Celsius_To_Fahrenheit res=new Celsius_To_Fahrenheit();
Scanner input=new Scanner(System.in);
System.out.println("Temperature in Celsius:"+cels_tO_fahre(32.0));
System.out.println("Temperature in Celsius:"+cels_tO_fahre(212.0));
System.out.println("Temperature in Celsius:"+cels_tO_fahre(50.0));
System.out.println("Temperature in Celsius:"+cels_tO_fahre(98.6));
//Dispay result
}
}
When the above code is executed, it produces the following result
Temperature in Celsius:0.0 Temperature in Celsius:100.0 Temperature in Celsius:10.0 Temperature in Celsius:37.0
Convert Fahrenheit into Celsius – C
C language
Program 2
// program to convert fahrenheit into celsius
//using function in C language
#include <stdio.h>
float convertFahToCels(float fh){
//defined user deined function with parameter
return ((fh-32)*5/9);
} //Convert fahrenheit into celsius
int main() {
//Calling function
//print celsius
float celsius1=convertFahToCels(50.00);
float celsius2=convertFahToCels(32.00);
float celsius3=convertFahToCels(212.00);
float celsius4=convertFahToCels(70.00);
float celsius5=convertFahToCels(210.00);
//display result on the screen
printf("The temperature in Celsius is=%.2f \n",celsius1);
printf("The temperature in Celsius is=%.2f \n",celsius2);
printf("The temperature in Celsius is=%.2f \n",celsius3);
printf("The temperature in Celsius is=%.2f \n",celsius4);
printf("The temperature in Celsius is=%.2f \n",celsius5);
return 0;
}
When the above code is executed, it produces the following result
The temperature in Celsius is=10.00 The temperature in Celsius is=0.00 The temperature in Celsius is=100.00 The temperature in Celsius is=21.11 The temperature in Celsius is=98.89
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
//Calling the function with argument
float celsius=fahrenheitToCelsius(00.00);
float celsius1=fahrenheitToCelsius(212.00);
float celsius2=fahrenheitToCelsius(100.00);
float celsius3=fahrenheitToCelsius(98.6);
//display result on the screen
cout<<celsius <<" Celsius"<<endl;
cout<<celsius1 <<" Celsius"<<endl;
cout<<celsius2 <<" Celsius"<<endl;
cout<<celsius3 <<" 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
-17.7778 Celsius 100 Celsius 37.7778 Celsius 37 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)
{
//Calling the function with argument
double celsius=FahrenheitTocelsius(98.6);
double celsius1=FahrenheitTocelsius(212);
double celsius2=FahrenheitTocelsius(32);
double celsius3=FahrenheitTocelsius(00);
//Dispay result on the screen
Console.WriteLine ("The temperature in Celsius: "+celsius);
Console.WriteLine ("The temperature in Celsius: "+celsius1);
Console.WriteLine ("The temperature in Celsius: "+celsius2);
Console.WriteLine ("The temperature in Celsius: "+celsius3);
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
The temperature in Celsius: 37 The temperature in Celsius: 100 The temperature in Celsius: 0 The temperature in Celsius: -17.7777777777778
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=70.00
#Declare and initialize variabe
#Calling the finction to calculate celsius
celsius=convertFahreToCels(fahrenheit)
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
70.0 degrees Fahrenheit is equal to 21.1 degree Celsius
Convert Fahrenheit into Celsius – PHP
PHP language
Program 6
<?php
//PHP code Convert Fahrenheit degrees to Celsius using function
function calc_Celsius(float $fahrenheit){
return ($fahrenheit-32) *5/9;
}//user define function to calculate Celsius
echo("The temperature in Celsius is: ");
//$celsius=round($celsius,3);
