GramsToCupsGrams to cups: granulated sugar
Granulated sugar weighs 200 g per US cup — far denser than flour. 100 g of sugar is exactly half a cup, 250 g is 1.25 cups and 500 g is 2.5 cups. Brown sugar packed is heavier still at 220 g per cup, while powdered sugar is just 120 g, the same as flour.

| Grams | Cups | Nearest kitchen measure | Tablespoons |
|---|---|---|---|
| 50 g | 0.25 | about 1/4 cups | 4 |
| 100 g | 0.5 | about 1/2 cups | 8 |
| 125 g | 0.63 | about 2/3 cups | 10 |

| 200 g | 1 | about 1 cups | 16 |
| 250 g | 1.25 | about 1 1/4 cups | 20 |
| 300 g | 1.5 | about 1 1/2 cups | 24 |
| 400 g | 2 | about 2 cups | 32 |

| 1000 g | 5 | about 5 cups | 80 |
Sugar type matters more than almost any other swap. A recipe written for granulated sugar measured out in powdered sugar would lose 40% of its sweetness by weight. Brown sugar is measured packed — pressed into the cup until it holds the cup's shape when turned out — which is why its per-cup weight tops the chart for dry ingredients.
Frequently asked questions
How many cups is 200 g of sugar?
Exactly 1 cup of granulated sugar. 200 g is one of the few round-number conversions in baking.
How many cups is 100 g of sugar?
Half a cup of granulated sugar (0.5 cups). For powdered sugar, 100 g is about 0.83 cups — roughly 3/4 cup plus a tablespoon.
Is caster sugar the same weight as granulated?
Close enough for home baking: caster (superfine) sugar is about 200–225 g per cup because its finer crystals pack slightly tighter. Use the granulated value and you will be within a few grams.
How many grams in a cup of brown sugar?
220 g, packed. Loose brown sugar can be 40 g lighter per cup, which is why recipes specify packed — and why weighing removes the ambiguity entirely.
