Brown Sugar Grams to Cups Converter
100g of packed brown sugar is about 0.47 US cups, using our reference of 213g per cup.
Enter your weight below to convert another amount of packed light or dark brown sugar.
Reference: King Arthur Baking's ingredient chart lists packed light or dark brown sugar at 213g per cup. We adopt that weight for this site's US Customary setting. The figures below apply to packed sugar, not sugar loosely poured into a cup.
Brown sugar grams to cups
This chart uses 213g per US Customary cup. Cup answers are approximate, displayed to a maximum of two decimal places.
| Brown sugar weight | Approximate US cups, packed |
|---|---|
| 25g | 0.12 |
| 50g | 0.23 |
| 75g | 0.35 |
| 100g | 0.47 |
| 125g | 0.59 |
| 150g | 0.7 |
| 175g | 0.82 |
| 200g | 0.94 |
| 213g | 1 |
| 225g | 1.06 |
| 250g | 1.17 |
| 300g | 1.41 |
| 350g | 1.64 |
| 400g | 1.88 |
| 500g | 2.35 |
| 750g | 3.52 |
| 1,000g | 4.69 |
These are decimal cups: 0.5 means half a cup. A displayed 0.47 cup is a little less than half a cup, not ½ cup exactly. Use the calculator's practical measuring suggestion when you need a combination of cups and spoons.

How to measure packed brown sugar
Packing removes gaps between the sugar and makes the measurement different from a loosely filled cup. Betty Crocker's measuring guidance recommends pressing brown sugar firmly into the cup with the back of a spoon.
- Spoon brown sugar into a dry measuring cup.
- Press it down with the back of a spoon, filling any gaps.
- Add more as needed, then level the sugar with the rim.
Use the packing method your recipe requests. If it specifically calls for loose or unpacked brown sugar, this packed reference is not a direct match.
When the recipe gives a gram amount and you have a scale, weigh the sugar directly. Packing matters when filling a volume measure; it does not change the gram amount you need to weigh.
How the conversion works
For this page's US Customary reference:
Cups = grams ÷ 213
For example, 200 ÷ 213 = about 0.94 cups. Keep the full result during the calculation and round only the displayed answer.
For the reverse calculation, multiply the cup amount by 213. That makes ½ cup 106.5g and ¼ cup about 53.3g, using the same reference and rounding gram answers to one decimal place.
You can switch direction in the calculator above or use the cups-to-grams converter with packed brown sugar selected.
Does light or dark brown sugar change the result?
Our selected reference covers both light and dark brown sugar when packed, so the calculator uses the same baseline for them. This does not mean every brand or cup you fill will weigh exactly the same.
Choose the type called for in your recipe. This page converts measurements; it does not establish that different sugars will produce the same baking result.
For other sugar types, use the granulated sugar converter or powdered sugar converter. Their references should not be used interchangeably with packed brown sugar.
What if my recipe gives a different cup weight?
Follow the recipe's own gram equivalent when it supplies one. Its ingredient or measuring method may differ from our reference. Avoid switching references halfway through a recipe simply to make a rounded cup amount look neater.
Cup size also matters. Our table stays on the US Customary setting. Selecting a 250mL metric cup in the calculator scales the baseline to about 225.1g per cup. That is our calculated adjustment, not a separate measurement published by the source.
See the cup-size guide for the available settings and the methodology for calculation and rounding details.
