Why Volume (Cups) to Weight (Grams) Varies

Converting cups to grams isn't a direct 1-to-1 calculation like converting inches to centimeters. This is because a cup is a measure of volume (how much space something takes up), while a gram is a measure of weight or mass.

For instance, a cup filled with heavy rocks will weigh significantly more than a cup filled with feathers. In baking, a cup of dense, packed brown sugar weighs about 213g, whereas a cup of airy, sifted flour weighs roughly 120g.

To properly convert your recipes, you must always take the specific ingredient density into consideration. Professional bakers often prefer using a digital scale because it removes the uncertainty of volume measurements, leading to much more consistent and reliable results.
