Baseline reference: 1 cup granulated sugar = 200g. In real kitchens, a practical range is usually 184g-216g per cup (8% band).
Why this happens: granule size, packing, and moisture level shift how much sugar fits in a cup.
Figures use the US cup (236.6 ml).1 cup of granulated sugar weighs 200 grams.
