1 Cup of Sugar in Grams
200 g in a US cup — and what that figure assumes
1 cup of granulated sugar weighs 200 grams, measured in a US cup.
That figure comes from one number: a full US cup of granulated sugar is 200 g. Everything else on this page is that number scaled.
Granulated sugar does not compact the way flour does, so scooping and spooning give almost the same weight. Fill the cup and level it off.
Whose cup you mean changes the answer. A 250 ml metric cup — the standard in the UK, Australia, New Zealand and Canada — is 5.7% larger than the 236.6 ml US cup, so one cup of granulated sugar is 211 g there rather than 200 g.
Why sugar is the easy one
One cup of granulated white sugar is 200 g (USDA FoodData Central; King Arthur Baking lists 198 g). Sugar crystals do not compress the way flour does, so however you fill the cup you land within a few grams.
The sugars that are different are the fine and the sticky ones. Caster (superfine) sugar is about 190 g per cup, powdered sugar 113–120 g unsifted, and brown sugar 220 g packed but only about 145 g loose. Never swap them cup for cup.
Where the 200 g figure comes from
- USDA FoodData Central: 1 cup of “Sugars, granulated” = 200 g (FDC ID 169655)
- King Arthur Baking ingredient weight chart: Sugar (granulated white), 1 cup = 198 g (chart)
This site uses 200 g per US cup of white granulated sugar, spooned and levelled. References checked September 2026.
1 cup of sugar in each cup standard
| Cup standard | Size | Grams | Ounces |
|---|---|---|---|
| US customary | 236.6 ml | 200 g | 7.05 oz |
| Metric (UK, AU, NZ, CA) | 250 ml | 211 g | 7.45 oz |
| Imperial (older UK) | 284 ml | 240 g | 8.47 oz |
A recipe that just says "cups" is almost always American. If yours came from a British, Australian or New Zealand source, take the metric row — on a 200 g measure the gap is 11.3 g.
Halving and doubling sugar
Recipes get scaled more often than they get followed exactly. These are the portions of granulated sugar a cook actually reaches for, already weighed out.
| Cups | Grams | Ounces | Tablespoons |
|---|---|---|---|
| ⅛ cup | 25 g | 0.88 oz | 2 |
| ¼ cup | 50 g | 1.76 oz | 4 |
| ⅓ cup | 66.7 g | 2.35 oz | 5.33 |
| ½ cup | 100 g | 3.53 oz | 8 |
| ⅔ cup | 133 g | 4.70 oz | 10.67 |
| ¾ cup | 150 g | 5.29 oz | 12 |
| 1 cup | 200 g | 7.05 oz | 16 |
| 1¼ cups | 250 g | 8.82 oz | 20 |
| 1½ cups | 300 g | 10.58 oz | 24 |
| 1¾ cups | 350 g | 12.35 oz | 28 |
| 2 cups | 400 g | 14.11 oz | 32 |
| 2¼ cups | 450 g | 15.87 oz | 36 |
| 2½ cups | 500 g | 17.64 oz | 40 |
| 3 cups | 600 g | 21.16 oz | 48 |
| 4 cups | 800 g | 28.22 oz | 64 |
| 5 cups | 1000 g | 35.27 oz | 80 |
| 6 cups | 1200 g | 42.33 oz | 96 |
1 cup of sugar in other units
| Unit | Amount |
|---|---|
| Grams | 200 g |
| Ounces (weight) | 7.05 oz |
| Pounds | 0.441 lb |
| Tablespoons | 16 |
| Teaspoons | 48 |
| Millilitres (the space it fills) | 237 ml |
This is white granulated sugar at 200 g per cup. Caster sugar is finer and weighs about 190 g, and powdered sugar is much lighter at 120 g, so those are different conversions.
1 cup of something else
The same cup holds a different weight of everything, because ingredients do not weigh the same for their size.
| Ingredient | Grams per US cup | 1 cup weighs |
|---|---|---|
| Flour | 125 g | 125 g |
| Butter | 227 g | 227 g |
| Milk | 244 g | 244 g |
Frequently asked questions
How many grams is 1 cup of sugar?
1 cup of granulated sugar is 200 grams in a US cup, based on 200 g per full cup. In a 250 ml metric cup it is 211 g.
Is that weighed or measured?
Measured, then weighed on a scale. Granulated sugar does not compact the way flour does, so scooping and spooning give almost the same weight. Fill the cup and level it off. A scale skips the question, which is why recipes that care about the result give grams.
How many tablespoons is 1 cup of sugar?
16 tablespoons, or 48 teaspoons — 12.5 g per tablespoon for granulated sugar.
How many ounces is 1 cup of sugar?
7.05 ounces by weight. That is not the same as fluid ounces — 1 cup is 8 US fluid ounces of space, whatever is filling it.
Why do different sites give different grams for 1 cup of sugar?
Because a cup is a volume and the weight depends on how it was filled, and on whose cup. This site uses 200 g per US cup. This is white granulated sugar at 200 g per cup. Caster sugar is finer and weighs about 190 g, and powdered sugar is much lighter at 120 g, so those are different conversions.
