Title [Package+Contents Weight(Listed Weight)] - Link
So overall expect to add an extra 15% to the products listed weight. Also don't forget to account for the box it all comes in!
My box was packaged by amazon, so they used a fairly thick box with a 1 inch cardboard insert on the bottom of the box.
So the weight of the packaging alone was around 1050g
