Why does baking soda weigh what it weighs?
Leavening agents are potent — a teaspoon too much baking soda makes cakes metallic and bitter, while a teaspoon too little leaves them flat. The density of baking powder and soda also varies by brand and age. Weighing avoids the confusion of "rounded" versus "level" teaspoons and produces consistent rise every time.
For baking soda specifically, 1 cup weighs 288g. 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.
