Why Grams Have Different Cup Values
Cups measure how much space an ingredient occupies, while grams measure how heavy that ingredient is. Different foods pack different amounts of mass into the same volume, which is why a conversion must always include an ingredient.
How to Measure More Accurately
For dry ingredients such as flour, spoon the ingredient into the cup and level it off, and do not press it firmly unless the recipe asks you to pack it. For baking, a digital kitchen scale is usually the simplest way to reproduce a gram measurement consistently.
