Why does buttermilk weigh what it weighs?
Dairy ingredients are mostly water by weight, so their density sits near 1 g/ml. Cream and condensed milk are denser because they contain more fat and dissolved solids; whey-based products like buttermilk are lighter. Volumetric measurements work reasonably well for liquid dairy — but weighing is still more reproducible.
For buttermilk specifically, 1 cup weighs 245g. 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.
