Measuring ½ US Cup of Granulated White Sugar in the Kitchen

Measured poured or spooned & leveled at a verified bulk density of 200g per US cup, ½ US cup of granulated white sugar weighs 100 grams (3.53 ounces). Measured using the dip scooped method (210g/cup), that same ½ cup holds 105g — a 5g difference in your mixing bowl.

Pour sugar directly into the measuring cup and level with a flat blade. Dry granulated sucrose crystals flow freely without trapping excessive air.
