One US cup of packed brown sugar weighs about 220 grams. That single number is what makes this conversion possible, and it is why baking by weight is more reliable than baking by volume.
Assumes firmly packed, which is the standard in US recipes. Volume measures depend on how the ingredient is packed into the cup, while a gram is a gram no matter how you scoop it.

The packed Brown Sugar gram to cup table below carries 11 pre-computed rows, from 25 g to 1000 g, so a figure can be checked against this page without typing anything into it. The page opens with grams of packed brown sugar already set to 220 g, so there is a finished result on screen before anything is typed. The formula is written out above with all 3 of its quantities named (cups, 220, grams), so the arithmetic can be followed by hand.

The formula
cups- Volume of packed brown sugar in US cups
220- Grams in one US cup of packed brown sugar
grams- Weight of the ingredient
How it works, step by step
- Enter your quantity of packed brown sugar.
- The tool applies the density of 220 g per US cup.
- The converted figure appears immediately, along with an ounce equivalent.
- Use the table for common recipe fractions without typing anything.
Worked examples
A standard single batch
If a recipe lists 440 g of packed brown sugar, that is 2 cups. Weighing is faster than levelling two separate cups.
Scaling a recipe by half
110 g of packed brown sugar is half a cup, which is the amount most often halved when scaling a recipe down.
Checking the 150 g row
The reference table lists Grams = 150 g, giving Cups: 0.68 cups, Ounces: 5.3 oz. Entering that above should reproduce the same figures — if it does not, the input is being read differently to the way the table assumes.
Frequently asked questions
How many grams are in a cup of packed brown sugar?
About 220 grams for a US cup. Assumes firmly packed, which is the standard in US recipes.
How many grams are in a tablespoon of packed brown sugar?
A US tablespoon is one sixteenth of a cup, so about 13.8 grams.
Why do different sources give different gram values?
Because volume measuring is genuinely imprecise. How you fill the cup changes the weight, sometimes by 20% or more for flours and powders. Published values assume a specific method — usually spooned and levelled — and this page uses that convention.
Should I bake by weight or volume?
By weight whenever a scale is available. It is more repeatable, faster with fewer dishes, and it is the reason professional recipes are written in grams.
How precise is the volume in cups?
Internally the maths runs at full double precision and the display keeps the significant figures that carry information, dropping the digits that are only rounding noise. Rounding happens at the display step alone, so nothing accumulates error as you change the input. The figure is reported in cups.
What formula does the Packed Brown Sugar: Grams to Cups Converter use?
It computes cups = grams ÷ 220, where cups is volume of packed brown sugar in US cups; 220 is grams in one US cup of packed brown sugar; grams is weight of the ingredient. The same expression is printed on the page above the inputs, so the result can be reproduced by hand or in a spreadsheet.
