Why does all-purpose flour weigh what it weighs?
Flour density varies dramatically with how it is measured. A cup of flour scooped straight from the bag can weigh up to 30% more than the same cup spooned and leveled. That is why bakers who care about consistency weigh their flour — small differences compound into dry, dense bakes or wet, sticky doughs.
For all-purpose flour specifically, 1 cup weighs 120g. That is the figure to plug into recipes calling for cup measurements when you want gram precision. ChefVault stores this density (and 118 others) so you never have to look it up twice.
Recipes that originated outside the United States almost always specify weight in grams. Translating these to US cup measurements introduces error in every step. The ChefVault app handles the math automatically — paste a recipe, hit convert, get a clean weight-based version.
