Temperature Conversion System

Temperature Conversion System


 Temperature of city in Fahrenheit degrees is input through the keyboard. write a program to convert this temperature into centigrade.


package com.company;

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
   // write your code here
        float fahrenheit, centigrade, temp;
        int choice;
        System.out.println("Temperature conversion system ");
        System.out.println("1. Fahrenheit to Centigrade");
        System.out.println("2. Centigrade to Fahrenheit");
        System.out.print("your choice : ");
        Scanner sc = new Scanner(System.in);
        choice = sc.nextInt();
        if (choice==1)
        {

            System.out.print("Fahrenheit : ");
            fahrenheit= sc.nextFloat();
            centigrade= (float) (-17.2222222*fahrenheit);
            System.out.println("After conversion in Centigrade : "+centigrade+" C");
        }
        else if (choice==2)
        {
            System.out.print("Centigrade : ");
            centigrade= sc.nextFloat();
            fahrenheit= (float) (33.8*centigrade);
            System.out.println("After conversion in Centigrade : "+fahrenheit+" F");
        }

        else {
            System.out.println("Enter correct choice");
        }
    }
}
output:-
Temperature conversion system 
1. Fahrenheit to Centigrade
2. Centigrade to Fahrenheit
your choice : 1
Fahrenheit : 23
After conversion in Centigrade : -396.1111 C

Process finished with exit code 0
