Density-accurate conversions for 40+ baking ingredients. All math runs instantly in your browser.
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.

Grams to cups, too
The converter runs in both directions — pick grams as the "from" unit and cups as the "to"
unit and it divides by the same density. A few anchors bakers reach for constantly: 250 g of
all-purpose flour is about 2 cups plus a tablespoon; 200 g of granulated sugar almost
exactly 1 cup; 100 g of butter just under half a cup (7 tablespoons). When a recipe gives
both cups and grams, trust the grams — that's the author's actual measurement.
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.
