For instance, 1 cup of flour equals 125 grams, while 1 cup of butter equals 227 grams and 1 cup of honey is equivalent to 340 grams. Ingredients with more density weigh more.

From the smallest measurement of a cup of flour to the largest, the difference is only slight: about ¾ ounce/22 grams or — if using our equivalent volume measurement — 2 ½ tablespoons.
