Brown Sugar — Cups to Grams Full Chart
Brown sugar is always measured packed unless the recipe states otherwise. Packing means pressing the sugar firmly into the measuring cup so there are no air gaps.

|---|---|---|
| 1/4 cup | 55g | 38g |
| 1/3 cup | 73g | 50g |
| 1/2 cup | 110g | 75g |

Why Does Sugar Weight Vary by Type?
Each type of sugar has a different crystal size and density. Granulated sugar has medium crystals that pack moderately. Powdered sugar is very fine and light — it contains cornstarch and has more air per cup. Brown sugar has moisture which makes it heavier when packed.
Baking Tip: Always use the same type of sugar your recipe specifies. Substituting granulated for powdered sugar changes the texture completely. If you must substitute, use 1 3/4 cups powdered sugar for every 1 cup of granulated sugar.
How to Measure Sugar Correctly
Granulated sugar: Scoop directly into the measuring cup and level off the top with a flat knife. Unlike flour, granulated sugar does not need to be spooned in — scooping is fine.
Brown sugar: Pack firmly into the measuring cup by pressing down with your fingers or a spoon. When you tip it out it should hold the shape of the cup. If the recipe says unpacked, spoon it in loosely without pressing.
Powdered sugar: Sift first to remove lumps, then spoon into the measuring cup and level off. Never scoop powdered sugar directly — it compacts and gives you too much. For grams to cups flour conversions see our guide on 1 cup of flour in grams.
