Weight.java

1. Write a java program that prompts the user to enter a weight in pounds and ounces and output the weight expressed in kilograms and grams. One pound is equals to 0.453592 kilograms. Name the program as Weight.java

Code :

import java.util.Scanner;
public class Weight {

static Scanner sc = new Scanner(System.in);
public static void main(String [] args)
        {
            //we need variables to hold values that the user will input

            double pounds;
            double ounces;
            double kg;
            double g;
            double kilograms;
            double grams;

           //variables are created
           //the program will ask the user to input number for pounds

            System.out.print("Enter pounds : ");
            pounds = sc.nextDouble();
          //pounds has been declared

          //the program will now ask the user to input number ounces
            System.out.print("Enter ounces : ");
            ounces = sc.nextDouble();
          //ounces has been declared

          //set conversion table : pounds to kilograms
            kg = 0.453592;
            g = 0.02845;

          //conversion computation
            kilograms = pounds*kg;
            grams = ounces*g;

          //display output
            System.out.println("Kilograms : " +kilograms);
            System.out.println("Grams : " +grams);

        }
}
