Weigh flour if you can. How you fill the cup changes what is in it: scooping straight from the bag packs flour down, so a scooped cup holds more than a spooned and leveled one.
Where this number comes from
USDA FoodData Central lists 1 cup of “Wheat flour, white, all-purpose, enriched, bleached” at 125 g (FDC ID 168894, 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).
