Convert volume to weight for any ingredient.
A cup is a measure of volume (236.6 mL), while a pound is weight (453.6g). The conversion depends entirely on the ingredient's density. 1 cup of flour weighs ~0.28 lbs (125g), but 1 cup of sugar weighs ~0.44 lbs (200g), and 1 cup of honey weighs ~0.75 lbs (340g). This is why baking recipes that use cup measurements can be inconsistent — the same "cup" of flour can vary by 30% depending on how it's scooped. Professional recipes worldwide use weight (grams) for precision. When converting recipes from US cups to weight, always specify the ingredient, as there's no universal cup-to-pound conversion.
