Why weigh granulated sugar instead of measuring cups?
A cup measures volume, but recipes really care about how much granulated sugar you add by weight. One US cup of granulated sugar is taken as 198 g here, cited from King Arthur Baking, and every conversion on this page routes through that figure. Volume-to-volume and weight-to-weight steps are exact, but the cup→gram crossing depends on product form and how the granulated sugar is packed, so a kitchen scale is the reliable way to hit the same result every time.
FAQ
How many grams are in a cup of granulated sugar?
One US cup of granulated sugar weighs about 198 g (source: King Arthur Baking). Because a cup measures volume, the exact weight shifts a little with how you fill it, so treat this as ±5% and weigh for precision.
How many grams are in a tablespoon of granulated sugar?
One tablespoon of granulated sugar is about 12.4 g, and one teaspoon about 4.13 g, since a US cup is exactly 16 tablespoons (48 teaspoons).

100 g of granulated sugar is about 0.505 cups. Use the converter above for any other weight — it works in both directions.
Is the cup-to-gram figure for granulated sugar exact?
The cup weight is a cited reference (King Arthur Baking); volume↔volume and weight↔weight conversions on this page are exact, but the cup→gram step depends on packing, humidity and brand, so it is best treated as ±5%. A kitchen scale removes the guesswork.
