One cup, side by side
What does a “packed” cup of brown sugar mean?
213 g is a packed cup — brown sugar pressed down into the cup rather than spooned in loose. That is the convention King Arthur's figure is measured under, and it is why the chart states it. A loosely filled cup weighs less, by an amount that depends on how hard you pressed, which is precisely why the packed figure is the one that gets published and the loose one does not.
