}Explanation
This converter is built around the packed brown sugar query, not a loose-fill estimate. It uses one consistent packed-cup assumption so common cup fractions can be turned into grams without mixing packed and unpacked measurements.
That matters because brown sugar changes significantly with packing. The same packed basis can also answer packed light brown sugar when the measuring method is the same. It covers the practical query pattern behind 1/4 cup brown sugar in grams, 1/3 cup brown sugar in grams, 2/3 cup packed brown sugar in grams, 2/3 cup light brown sugar in grams, 3/4 cups brown sugar in grams, 2 cups brown sugar in grams, and how much 1 cup of brown sugar weighs.
Brown Sugar uses a reviewed reference of 213 grams per US cup in this dataset. Evidence status: high-confidence. Source basis: King Arthur weight chart (packed)
Moisture, preparation, particle size, packing, and temperature can change bulk density, so match the ingredient form named on the page.
