I got project do convert from cm to inch. I did it: how can i round my number with Math.round? 

public class Centimer_Inch

{

public static void main (String[] args)

{

        // 2.54cm is 1 inch

       Scanner cm = new Scanner(System.in); //Get INPUT from pc-Keyboard

       System.out.println("Enter the CM:"); // Write input

       double centimeters = cm.nextDouble();

       double inches = centimeters/2.54;

       System.out.println(inches + " Inch Is " + centimeters + " centimeters");

     }

}
