One cup of granulated sugar weighs 198 grams. Sugar's free-flowing crystals pack far more consistently than flour, so the number barely moves between cooks — as long as you do not shake the cup down or press the sugar in.

How to measure granulated sugar properly
Pour, level, done. Granulated sugar needs none of flour's ceremony: pour or spoon it into the cup, level the top, and you have 198 grams within a gram or two. The two mistakes to avoid are shaking the cup to settle more in, and pressing it down — both quietly add sugar the recipe did not ask for.
Break up humidity lumps first. Sugar stored in a damp kitchen clumps into rocks that bridge across the cup and leave air pockets. A quick stir or a rub between your fingers before measuring keeps the fill honest.
Cane or beet makes no difference. Granulated sugar weighs 198 grams per cup whether it came from cane or beet, and white sugar is white sugar in the scales whatever the bag's branding says — save the distinctions for flavour debates, not for the weighing.
Frequently asked questions
How many grams are in a cup of granulated sugar?
198 grams. That is the standard King Arthur Baking figure used throughout GramChef, and it holds for any ordinary white granulated sugar, cane or beet, poured or spooned into the cup and levelled.
How many grams are in half a cup of granulated sugar?
99 grams — exactly half of 198. A quarter cup is 50 grams (49.5, rounded) and a tablespoon of granulated sugar weighs 12.4 grams, which is why so many recipes round a tablespoon of sugar to 12 grams.
How many cups is 250 grams of granulated sugar?
About 1.26 cups — call it 1¼ cups. The maths is 250 ÷ 198 ≈ 1.26. Sugar is forgiving at this scale, but for caramels and meringues, where ratios drive the result, weigh the 250 grams rather than trusting the fraction.
