Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: All-purpose flour density varies by measuring technique. Spooned into cup: ~125g. Scooped (packed): ~150g. Sifted: ~110g. USDA FoodData Central uses spooned method as standard. King Arthur Baking recommends 120g (sifted standard). The difference matters in baking — use a scale for best results.
About All-Purpose Flour Density
The density of all-purpose flour determines how much it weighs per unit of volume. At 0.521g/ml, 1 US cup (240ml) of all-purpose flour weighs 125g under USDA standard conditions.
1 teaspoon = 1/48 cup = 5ml. For all-purpose flour, this equals 2.6g per teaspoon. Teaspoon measurements are critical for spices, extracts, and leavening agents where small differences have large effects. A kitchen scale is especially recommended for teaspoon-level precision.
