Java program to convert days to milliseconds

Following program shows you how to convert days to milliseconds.
In this program we get days from user once we get those we need to multiply with 24 so that we get in hours, once we get hours 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 MathUnitConversions15 {

	public static void main(String[] args) {

		long days;

		Scanner in = new Scanner(System.in);

		System.out.println("Please enter days:");

		days = in.nextLong();
		long milliseconds = days * 24 * 60 * 60 * 1000;

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

Output:

Please enter days:
2
172800000 Milliseconds
