Java program to convert hours to milliseconds

Following program shows you how to convert hours to milliseconds.
In this program we get hours from user, once we get those we need to multiply with 60 so that we get in mintues, once we get mintues we need to multiply with 60 so that we get in seconds, once we get seconds we need to multiply with 1000 so that we get in milliseconds

import java.util.Scanner;

public class MathUnitConversions12 {

	public static void main(String[] args) {
	
		long hours;
		
		Scanner in = new Scanner(System.in);

		System.out.println("Please enter hours:");
		hours = in.nextInt();

		long milliseconds = hours * 60 * 60 *1000;

		System.out.println(milliseconds + " Milliseconds");
	}
}

Output:

Please enter hours:
