About cups All-Purpose Flour (cups)
Cups of All-Purpose Flour. Measured by US cup (= 240 mL = 16 US tablespoons = 48 US teaspoons per FDA 21 CFR 101.9). The cup is the dominant US baking + cooking volume unit, but actual density varies significantly by how the ingredient is packed (scooped vs spooned-and-leveled — a 1-cup scoop of flour can range from 110 g to 150+ g depending on technique, which is why precise bakers use mass measurement in grams). Always level with a flat edge (the back of a knife) for accurate volumetric measurement. All-purpose flour (AP flour) is wheat flour with moderate protein content (10-12% per General Mills, King Arthur, Pillsbury, Gold Medal milling specs) — the workhorse of American home baking, suitable for cookies, quick breads, pancakes, pie crusts, and most savory cooking. Milled from a blend of hard and soft wheat varieties to balance gluten development. Density ~0.529 g/mL (1 cup = 125 g per King Arthur Baking standard; FDA RACC nutrient declaration label uses 30 g serving). Bleached AP flour (chemically treated with chlorine gas, benzoyl peroxide, or potassium bromate) is the US norm; unbleached AP is preferred for artisan baking, sourdough starter feeding, and yeasted breads. European 'plain flour' Type 405 (Germany) or 00 (Italy) is roughly equivalent. Storage: airtight container, 6-12 months pantry life, freezer-safe for whole-wheat varieties. Density: 0.529 g/mL (used to convert volume measurements to mass).
About ounces All-Purpose Flour (ounces)
Ounces of All-Purpose Flour. Measured by US avoirdupois ounce (= 28.349523125 g exactly per NIST SP 811 — distinct from fluid ounce which is a volume unit). Mass-ounce measurement is preferred in US butcher/bakery/professional contexts where precision matters but the recipe uses imperial customary units. Common US baking ingredient packages list both ounces (mass) + grams: a stick of butter = 4 oz = 113 g; a 'pound' of flour = 16 oz = 454 g. CRITICAL: do NOT confuse with the troy ounce (~31.1 g — used only for precious metals) or the fluid ounce (volume unit = 29.57 mL).
