Measuring ¼ US Cup of All-Purpose Flour in the Kitchen

Measured spooned & leveled at a verified bulk density of 120g per US cup, ¼ US cup of all-purpose flour weighs 30 grams (1.06 ounces). Measured using the dip-and-sweep scooped method (142g/cup), that same ¼ cup holds 35.5g — a 5.5g difference in your mixing bowl.

Fluff flour with a fork, spoon gently into the measuring cup until mounded, and sweep level with a straight knife. Never pack or tap the cup, which compresses flour up to 142g.
