Why does water weigh what it weighs?
Most cooking liquids are close to water density (1 g/ml), but not all. Honey, syrup, and soy sauce are noticeably denser because of dissolved solids. Oils and alcohols are less dense. For baking and emulsions where ratios matter, weighing avoids the surface-tension errors of reading a meniscus on a measuring cup.
For water specifically, 1 cup weighs 237g. 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.
