52 grams of cereal equals how many cups?
"Cups" is a measurement of volume, or "how much cereal occupies
this space?" Grams is a measurement of weight. Rice crispies, for
example, are puffed rice. There is plenty of air in them making
them a lightweight cereal. Grape nuts are a solid dense cereal,
making them heavier than rice crispies. There is no accurate answer
to this question.
