About cups Peanut Butter (cups)
Cups of Peanut Butter. 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. Peanut butter is a paste made from ground roasted peanuts (Arachis hypogaea — actually a legume, not a true nut). Density ~1.080 g/mL (slightly denser than water; 1 cup = 258 g per Skippy/Jif standard). Smooth ('creamy') vs 'crunchy' (with peanut pieces) varieties; both must contain ≥90% peanuts per FDA standards for the 'peanut butter' designation, allowing up to 10% additional sweeteners + salt + emulsifiers + hydrogenated oils to prevent oil separation. 'Natural' peanut butter (Smucker's Natural, Trader Joe's, MaraNatha) is just peanuts + salt — oil separation requires stirring before use + refrigeration after opening. Major US grocery brands: Jif (PepsiCo, the #1 by sales), Skippy (Hormel), Peter Pan (ConAgra), Smucker's. Peanuts are high in protein (~25%) + fat (~50%, mostly monounsaturated + polyunsaturated), making peanut butter a popular vegan + vegetarian protein source. Allergen warning: peanut allergy affects ~2% of US children + ~0.5% of adults (CDC); peanut butter is one of the most common severe food-allergen triggers. Used in: peanut butter + jelly sandwiches, baking (cookies, brownies), Thai + Indonesian cuisines (satay sauce, gado-gado), smoothies, energy bars. Density: 1.080 g/mL (used to convert volume measurements to mass).
About ounces Peanut Butter (ounces)
Ounces of Peanut Butter. 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).
