[android-developers] size in inches

I'm trying to make a routine that gets the width and height of a device in inches:

Here's what I came up with:

public void get_display_size() {

DisplayMetrics metrics = new DisplayMetrics();

getWindowManager().getDefaultDisplay().getMetrics(metrics);

float width_in = metrics.widthPixels / metrics.xdpi;

float height_in = metrics.heightPixels / metrics.ydpi;

}

Does this look good?

Or is there a better way?
