30 Grams of Brown Sugar to Cups
⅛ cup in a US cup — and what that looks like with a measuring spoon
30 grams of packed brown sugar is about 6½ teaspoons — ⅛ of a US cup. At this size measure it with spoons; a cup measure cannot show it.
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, though not much at this weight. A 250 ml metric cup — the standard in the UK, Australia, New Zealand and Canada — holds about 5.7% more than the 236.6 ml US cup, but 30 g of packed brown sugar still rounds to ⅛ cup in both: 0.14 US cups against 0.13 metric.
Round to the nearest measure in a standard cup set — ¼ cup — and you are 25 g over, about 83% of the amount.
30 g of brown sugar in each cup standard
| Cup standard | Size | Grams per cup | Cups |
|---|---|---|---|
| US customary | 236.6 ml | 220 g | ⅛ |
| Metric (UK, AU, NZ, CA) | 250 ml | 232 g | ⅛ |
| Imperial (older UK) | 284 ml | 264 g | ⅛ |
A recipe that says "cups" without saying which one is almost always American. At 30 g it barely matters for packed brown sugar — both cups round to the same measure — but on a larger batch the 5.7% gap compounds.
How to measure 30 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.
- Measure 6½ teaspoons rather than trying to read a cup fraction.
- 30 g is 2.18 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 30 grams of brown sugar?
30 grams of packed brown sugar is ⅛ of a US cup, which is easier to measure as 6½ teaspoons. A 250 ml metric cup rounds to the same ⅛ of a cup.
What is the easiest way to measure 30 g of brown sugar?
2 tablespoons plus ½ 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 30 g of brown sugar the same in cups in the UK?
Near enough. A UK, Australian, New Zealand or Canadian metric cup is 250 ml against the US cup's 236.6 ml, so the exact answers differ — 0.14 US cups against 0.13 metric — but both round to ⅛ cup, and at this weight you can use either.
Can I just use ¼ cup instead?
¼ cup of packed brown sugar weighs about 55 g, so you would be 25 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 30 grams?
30 grams is 1.06 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.
