Convert Cups to Grams for Any Baking Ingredient
American recipes measure by volume — cups, tablespoons, teaspoons — while the rest of the world (and every professional kitchen) measures by weight. This cups to grams converter bridges the gap with ingredient-specific densities, because a cup of flour, a cup of sugar, and a cup of honey all weigh completely different amounts: 120 g, 198 g, and 340 g respectively.
Our densities follow the King Arthur Baking ingredient weight chart — the standard reference US test kitchens use — cross-checked against USDA data. Flours assume the spoon-and-level method; brown sugar is measured packed, as recipes intend. Unlike AI-powered converters, everything here is precomputed and instant: no server round-trip, no waiting, and it works offline once the page loads.

Use the converter above for the full ingredient list — flours, sugars, fats, dairy, leavening, nuts and add-ins — in any direction: cups to grams, grams to cups, tablespoons to grams, or ounces to anything. For butter specifically — sticks, cups, tablespoons — the butter converter shows every equivalent at once, and once your recipe is in grams the recipe scaler can resize it cleanly.
