Formula px to dp, dp to px android

I am trying to calculate a variable amount of pixels to density independent pixels and vice-versa.

This formula (px to dp): dp = (int)(px / (displayMetrics.densityDpi / 160)); does not work on small devices because it is divided by zero.

This is my dp to px formula: 

px = (int)(dp * (displayMetrics.densityDpi / 160));

Could someone give me some pointers?

Feel free to use this method I wrote:

int dpToPx(int dp)
{
    return (int) (dp * getResources().getDisplayMetrics().density + 0.5f);
}
