    How we got 120 g

    Spooned & leveled. King Arthur: 1 cup = 4 1/4 oz = 120 g. Site uses the King Arthur figure because US home recipes assume flour spooned into the cup and leveled, which is how King Arthur weighs it; USDA's cup weight is typically higher (dipped/unspecified method).

    • USDA FDC SR Legacy 168894 (bleached, enriched): 125 g per cup
    • USDA FDC SR Legacy 168936 (unbleached, enriched): 125 g per cup

    Scooping straight from the bag compacts flour and can add 15-25% weight; sifting lowers it. Weighing is the only reliable method.
