Granulated Sugar grams to cups
One US cup of granulated sugar weighs about 200 grams.
Standard white sugar, refined into hard, uniform crystals. Because the crystals do not compress, a cup weighs almost exactly the same however you fill it — one of the few ingredients where volume measuring is genuinely reliable.

Granulated Sugar in tablespoons, teaspoons and millilitres
Cup fractions stop being useful below about a quarter of a cup. These are the measures to reach for when the amount is small.

One US cup is 16 tablespoons or 48 teaspoons, whatever is in it — those two are volume measures, so no density is involved.
Measuring notes
No technique required. Sugar crystals will not compact, so scoop, pour or spoon it as you like and the weight barely moves.

Granulated Sugar — common questions
How many grams is 1 cup of sugar?
One cup of granulated sugar weighs about 200 grams. Sugar crystals do not compress the way flour does, so this figure stays reliable however you fill the cup.
How many cups is 100 grams?
It depends entirely on the ingredient. 100 grams of all-purpose flour is about 0.83 cups, but 100 grams of honey is only about 0.29 cups, because honey is far denser. Grams measure weight and cups measure volume, so there is no single conversion that works for everything.
Why do different converters give different answers?
Mostly because they assume different measuring techniques. Flour spooned gently into a cup weighs around 120 grams; the same cup dipped straight into the bag can hold 140 grams. Both figures are defensible, so two sites can disagree by 15% and neither is lying. We publish separate figures for each technique rather than picking one.
Are these conversions exact?
No, and no weight-to-volume conversion can be. Density shifts with packing, humidity, grind and brand. Treat every result here as a close approximation. If precision matters, weigh your ingredients.
Should I use grams or cups?
Grams, whenever you have a scale. Weight does not change with how you fill the cup, so it is reproducible, and weighing straight into the bowl means less washing up. Cups are convenient, not accurate.
