Frequently Asked Questions
How many grams is a cup of brown sugar?
1 cup of brown sugar, firmly packed into the cup is 213 grams.
What should I know about measuring brown sugar?
This conversion is for brown sugar, firmly packed into the cup, and brown sugar is measured packed, not spooned and leveled like flour or granulated sugar — pressing it into the cup removes air pockets, which is why it weighs more per cup than white sugar despite looking similar in the bag.
Should I use a kitchen scale instead of cups?
For baking specifically, yes if precision matters — weight doesn't vary with how tightly an ingredient is packed, so it's more consistent than volume measurement. This converter helps translate a cup-based recipe to weight, or a weight-based recipe back to cups.
