Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Peanut butter density depends heavily on style. Creamy/smooth: 1 cup = 258g. Natural peanut butter (oil separated): similar weight but harder to measure consistently. Crunchy adds variability. 2 tablespoons peanut butter = ~32g.
