Using function or method to Write temperature conversion : Fahrenheit into Celsius

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
