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.

Frequently asked questions
How many oz is 1 cup of Brown sugar?
1 cup of Brown sugar is 7.51 oz, because one US cup of Brown sugar weighs 213 g. That single measured figure is the whole conversion — every other unit on this page is derived from it.
How many cups is 4 oz of Brown sugar?
4 oz of Brown sugar is 0.532 cups. It is the same conversion read backwards, so this page and its reverse always agree.
Is that ounces by weight, or fluid ounces?
By weight. dishscale's ounce is the international avoirdupois ounce, 28.3495 g, so one cup of Brown sugar is 7.51 oz. A US fluid ounce is a volume and there are eight of them to the cup, so that same cup is 8 fl oz at the same time. The two readings coincide only for an ingredient that happens to weigh eight ounces to the cup.
Where does dishscale's figure for Brown sugar come from?
One US cup of Brown sugar is 213 g. The dataset records that as: “King Arthur Baking”. That is the King Arthur Baking ingredient weight chart. Every ingredient on the site carries the reference its weight came from, so any number here can be checked — and corrected if the source disagrees.
