Granulated Sugar: Cups to Grams
Quick answer: One US cup of granulated sugar weighs about 200 grams (7.1 oz), and one tablespoon about 13 g.
US recipes measure granulated sugar in cups; the rest of the world weighs it. Convert any amount in either direction — and measure it the way the chart assumes: pour and level — sugar doesn't compact, so it's the most forgiving cup in baking.

| ⅓ cup | 67 g | 2.4 oz |
| ½ cup | 100 g | 3.5 oz |
| ⅔ cup | 133 g | 4.7 oz |
| ¾ cup | 150 g | 5.3 oz |
| 1 cup | 200 g | 7.1 oz |
| 1½ cups | 300 g | 10.6 oz |
| 2 cups | 400 g | 14.1 oz |
How it works
Cups measure volume and grams measure weight, so the conversion runs through density: granulated sugar packs about 200 g into a US cup (237 ml). Volume is only as accurate as your technique — pour and level — sugar doesn't compact, so it's the most forgiving cup in baking. That variability is exactly why serious baking recipes list grams, and why a $15 kitchen scale upgrades every bake. If your recipe uses metric cups (250 ml), the weights run about 5% higher.
Frequently asked
How many grams are in a cup of granulated sugar?
About 200 grams (7.1 oz) per US cup, measured properly. A tablespoon is about 13 g.
How many cups is 250 g of granulated sugar?
About 1.25 cups. Divide any gram amount by 200 to get cups — or flip the converter above to grams and it does it for you.
Do other sugars weigh the same per cup?
No — packed brown sugar is ~220 g per cup, powdered sugar only ~120 g, and superfine (caster) ~225 g. Each has its own page here; don't swap them by volume.
