Different ingredients pack differently, so a cup of flour and a cup of honey don't weigh the same. Pick your ingredient below to get an accurate gram conversion.
Volume measurements like cups are convenient but imprecise, because how densely an ingredient is packed changes its weight. A cup of sifted flour can weigh 15–20% less than a cup of flour scooped straight from the bag. Weighing ingredients in grams removes that variability, which is why most professional and European recipes use weight instead of volume.
This calculator uses standard gram-per-cup weights for common baking and cooking ingredients, based on how each ingredient is typically measured (spooned-and-leveled for dry ingredients, packed for brown sugar).
Source: Gram weights per cup are based on King Arthur Baking's ingredient weight chart, the standard reference used by U.S. baking cookbooks.
Weight depends on how densely a food packs into a cup, which varies with particle size and moisture. Sugar granules pack more tightly than flour, so a cup of sugar weighs more than a cup of flour even though the volume is identical.
Brown sugar recipes almost always assume it's packed firmly into the cup, which is why this calculator uses the packed gram weight (about 220g per cup) rather than the loose weight.
Yes. A kitchen scale removes the variability caused by scooping, packing, and settling, which is why weight is the standard in professional baking and in most non-U.S. recipes.
