public static float convertPixelsToDp(float px, Context context) {
        Resources resources = context.getResources();
        DisplayMetrics metrics = resources.getDisplayMetrics();
        return px / ((float) metrics.densityDpi / DisplayMetrics.DENSITY_DEFAULT);
    }
This method converts device specific pixels to density independent pixels.

@param px      A value in px (pixels) unit. Which we need to convert into db
@param context Context to get resources and device specific display metrics
@return A float value to represent dp equivalent to px value
