No scale? 120 g of powdered sugar is about 1 cup, or roughly 1 cup using standard US measuring cups and spoons. Spoon it in and level off the top instead of scooping, which packs in extra.
At exactly 120 grams you hit one level US cup, the clean reference point every other amount on this page is measured against. It is the standard single addition when building American buttercream, enough to sweeten and stiffen about half a stick of creamed butter, and the typical pour for a batch of glaze covering one Bundt cake. Doubling or halving from here is trivial: 240 grams gives two cups, 60 grams gives half a cup.
