Brown Sugar (Packed): cups to grams

1 US cup of brown sugar
About 213 grams
About 7.5 oz by weight · US cup estimate

The figures here assume packed brown sugar. Loose spoonfuls leave more air in the cup, so this chart can overestimate their weight. If your recipe explicitly asks for loosely packed sugar, follow that instruction.

Brown Sugar (Packed) cups to grams

Estimated weight of brown sugar in US customary cups. Grams are rounded to whole numbers; oz means weight ounces, not fluid ounces.
Cups Grams Ounces
⅛ cup 27 g 0.94 oz
¼ cup 53 g 1.88 oz
⅓ cup 71 g 2.5 oz
½ cup 107 g 3.76 oz
⅔ cup 142 g 5.01 oz
¾ cup 160 g 5.64 oz
1 cup 213 g 7.51 oz
1½ cups 320 g 11.27 oz
2 cups 426 g 15.03 oz
3 cups 639 g 22.54 oz
4 cups 852 g 30.05 oz

Brown Sugar (Packed) grams to cups

Approximate US cup or US tablespoon equivalents for brown sugar. Cups and tablespoons each show the whole amount, not amounts to add together.
Grams US cups US tbsp

50 g 0.23 3.8
100 g 0.47 7.5
125 g 0.59 9.4
150 g 0.70 11.3
200 g 0.94 15.0
250 g 1.17 18.8
300 g 1.41 22.5
400 g 1.88 30.0
500 g 2.35 37.6

Measuring tip

Break up lumps, press the sugar into the cup in layers and level the top. Packed sugar should hold the cup’s shape when turned out. Weighing avoids guessing how firmly another cook packed it.

Half a cup of packed brown sugar

Use this estimate when the recipe calls for a packed half cup. A loosely filled half cup contains more air and should not be expected to match the same weight.

Choose the cup size in the recipe

The same ingredient fills a larger cup with more weight. These comparisons keep the stored density fixed and change only the cup capacity. Use a marked measuring cup, not a drinking mug.

  • US customary: the basis of both ingredient tables above. The tablespoon column uses 16 US tablespoons per cup.
  • UK recipes: follow the author’s stated cup capacity or use the supplied grams or millilitres. A UK recipe does not automatically mean a 250 mL cup.
  • Fluid ounces: US and UK markings describe different volumes. They are separate choices in the volume converter below, and neither is an ounce by weight.

Convert cooking volumes

Use this calculator to change between cups, millilitres, decilitres and spoons. Select the measurement system printed in the recipe. It converts volume only; use the ingredient tables above for estimated grams.

Questions

How many grams is 1 cup of brown sugar?

This chart estimates about 213 grams per US customary cup of brown sugar. It is a stored kitchen estimate, not an exact weight for every brand or measuring method. Use the recipe’s gram amount if one is given.

How many cups is 100 g of brown sugar?

Using this estimate, 100 g is about 0.47 US cups. The table also expresses that same total volume as approximately 7.5 US tablespoons; those spoonfuls are not extra to add to the cups.

Why does my recipe give a different weight per cup?

Cup size, preparation and the way the ingredient fills the measure can differ. A loose powder has air between its particles; packing it makes more fit. Liquids also have different densities. A recipe’s own weight is the better choice for reproducing that recipe.

Which cup should I use for a US or UK recipe?

These charts use the US customary cup, about 236.59 mL. Use the author’s stated capacity for a UK recipe rather than choosing by country alone. If it specifies a 250 mL metric cup, the same density estimate gives about 225 g of brown sugar per cup. The 240 mL US legal cup is another distinct setting.

How to use the estimate and check a reference

The tables scale ToolsNow’s stored estimate of 213 g per US customary cup of brown sugar. To convert another cup amount, multiply it by that weight. To work backwards from grams, divide by the same weight. Round at the end rather than adding together already-rounded table rows.

For comparison, King Arthur Baking’s ingredient weight chart gives weights with preparation notes, including packed brown sugar and unsifted confectioners’ sugar. These pages retain ToolsNow’s own estimates; they are not a reproduction of that chart. When your recipe or product gives a different weight, prefer that more specific reference.
