1 cup sugar in grams
Granulated sugar cups to grams converter
One cup of granulated white sugar weighs 200 grams. Sugar crystals are uniform and resist compacting, so the cups-to-grams ratio barely shifts with how you measure — there is no spooned-vs-scooped discrepancy for granulated sugar. The two sources we cite (King Arthur Baking, Doves Farm) agree to within ~1% (198 g vs 200 g), well within rounding.

Convention
Two numbers? Here's why
Why two numbers? The cup-to-gram convention
Granulated sugar is one of the rare ingredients where the cup-to-gram conversion is unambiguous. King Arthur Baking's chart lists 198 g/cup; Doves Farm's chart lists 200 g/cup. The two are within ~1% of each other — inside the rounding tolerance of a kitchen scale — so we display a single convention at 200 g/cup. Sugar's crystal size does not change with how you spoon or scoop it; the cup volume is what determines the weight.

How we cross-checked these numbers
Each density value is cross-referenced against at least two independent published sources. When two sources disagree by more than 5%, both conventions are shown in the "Why two numbers?" block above instead of silently picking one.

Note on accuracy
KAF lists 198 g/cup; Doves Farm lists 200 g/cup. The two sources disagree by ~1% (well under the PRD §6 5% threshold), so a single convention is shown. 200 g/cup is the headline value because it matches the typical AI Overview / search-snippet answer for '1 cup sugar in grams' and is within rounding of the KAF chart.
