All-Purpose Flour

The most common flour used in baking. Tightly packed all-purpose flour weighs more, while sifted flour is lighter — making density-accurate conversion essential.

Why density matters

All-Purpose Flour has a density of 0.5 g/ml. Compare that to water at 1.0 g/ml — a lighter ingredient will give a lower gram count per cup. Generic converters that assume 240g per cup for everything would give you 120g more than the actual weight — which can ruin precision bakes.
