About CupWeights

Most grams-to-cups charts give one number with no source, and different charts disagree. CupWeights shows where each number comes from: USDA FoodData Central for the weight we use, and King Arthur Baking's chart alongside, so you can see when a difference is really about how the cup was filled.
