Wich box is greater, a 1.5 - pound box of raisins or a 650-gram box of rocks?

The first step of this is to convert them both to the same unit. since 1 pound is equal to. 45 kg,.45*1.5=.68 kg. now we need to convert kg to grams, when we do this we get 680 grams of raisins and 650 grams of rocks. we can obviously see that the box of raisins is heavier.
