Key Facts about All-Purpose Flour
Scoop vs. Spoon Method
Dipping your measuring spoon directly into the flour bag packs the flour, increasing density by up to 25% (up to 3,200 mg/tsp).
Cake vs. Bread Flour
Cake flour is finely milled with low protein, weighing ~2,170 mg per tsp sifted, while higher-protein bread flour weighs ~2,640 mg.
Why Weighing is Essential
In professional pastry baking, weight measurements in mg or grams ensure consistent crumb texture and avoid dry, dense bakes.
How to Convert a Teaspoon of All-Purpose Flour to Milligrams
Teaspoons measure volume. Milligrams measure mass. To convert between them you need the substance density.
For All-Purpose Flour, the density is approximately 0.529 g/mL. Flour density averages ~0.529 g/mL when spooned and leveled. 1 US tsp = ~2,607 mg.
Formula
mg = tsp × 4.92892 mL × 0.529 g/mL × 1000Example: 1 tsp of All-Purpose Flour = 1 × 4.92892 × 0.529 × 1000 = 2,607.4 mg
