How Much Is 660 Grams of Brown Sugar in Cups?
660 grams of brown sugar equals 3.00 cups. Brown sugar has a density of 220g per cup. Because grams measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 660 grams of brown sugar
- 1 cup of brown sugar = 220g
- 660g ÷ 220g/cup = 3 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Brown sugar should always be firmly packed into the measuring cup. Loosely measured brown sugar can weigh 15-20% less than packed.

Understanding the Units
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
