USDA weighs cake flour unsifted, with the cup dipped into the bag and leveled: 137 g. Recipes that call for sifted cake flour fill the cup more loosely, so a sifted cup weighs less; if the recipe gives grams, weigh it.
Where this number comes from
USDA FoodData Central lists 1 cup unsifted, dipped of “Wheat flour, white, cake, enriched” at 137 g (FDC ID 169723, SR Legacy).
Everything else is worked out from that figure: spoons from 1 cup = 16 tablespoons = 48 teaspoons, and ounces and pounds from their exact definitions (1 oz = 28.349523125 g, 1 lb = 453.59237 g, NIST).
