100 Grams of Brown Sugar to Cups
½ cup in a US cup — and what that looks like with a measuring spoon
100 grams of packed brown sugar is ½ cup in a US cup. In the kitchen that is ¼ cup, 3 tablespoons plus ¾ teaspoon.
Grams weigh and cups fill, so the answer only exists once you say what is in the cup. A US cup of packed brown sugar weighs 220 g, and every figure on this page comes from that one number.
It also depends on whose cup you mean. In a 250 ml metric cup — the standard in the UK, Australia, New Zealand and Canada — 100 g of packed brown sugar is ⅜ cup, because that cup holds about 5.7% more than the 236.6 ml US cup.
Round to the nearest measure in a standard cup set — ½ cup — and you are 10 g over, about 10% of the amount.
100 g of brown sugar in each cup standard
| Cup standard | Size | Grams per cup | Cups |
|---|---|---|---|
| US customary | 236.6 ml | 220 g | ½ |
| Metric (UK, AU, NZ, CA) | 250 ml | 232 g | ⅜ |
| Imperial (older UK) | 284 ml | 264 g | ⅜ |
A recipe that says "cups" without saying which one is almost always American. If it came from a British, Australian or New Zealand source, use the metric row.
How to measure 100 g of brown sugar without scales
Brown sugar is measured packed: press it firmly into the cup so it holds the shape of the cup when tipped out. That is what a recipe means by "1 cup packed".
Packed brown sugar is 220 g per cup. Loose, unpacked brown sugar is only about 170 g, so the same cup can differ by a quarter depending on how hard it was pressed.
- Build it as ¼ cup, 3 tablespoons plus ¾ teaspoon rather than guessing at ½ of a cup.
- 100 g is 7.27 tablespoons of packed brown sugar, at 13.75 g per tablespoon.
- A digital scale removes the question entirely, and costs less than the ingredients it saves.

Frequently asked questions
How many cups is 100 grams of brown sugar?
100 grams of packed brown sugar is ½ cup in a US cup, based on 220 g per cup. A 250 ml metric cup gives ⅜ cup.
What is the easiest way to measure 100 g of brown sugar?
¼ cup, 3 tablespoons plus ¾ teaspoon — built from a standard cup and spoon set. Brown sugar is measured packed: press it firmly into the cup so it holds the shape of the cup when tipped out. That is what a recipe means by "1 cup packed".
Is 100 g of brown sugar the same in cups in the UK?
No. A UK, Australian, New Zealand or Canadian metric cup is 250 ml against the US cup's 236.6 ml, so 100 g of packed brown sugar is ⅜ cup there and ½ cup in the US.
Can I just use ½ cup instead?
½ cup of packed brown sugar weighs about 110 g, so you would be 10 g over. For a sauce or a soup that is fine; for a cake, where the flour-to-liquid ratio sets the crumb, weigh it.
How many ounces is 100 grams?
100 grams is 3.53 ounces by weight. Unlike cups, that answer is the same whatever you are measuring — ounces weigh, fluid ounces fill, and they are not the same unit.
