How much Special K is two grains?

How much special k with red berries would count as two grains? 

1 serving of grains is 1oz, or approximately 30 grams. 

A serving size of cereal is usually 30 grams, so get a food scale and measure out 60 grams-- which would be "2 servings"

**though I would ditch the special k, because it is total garbage. 

Two grains would be two servings - in this case, I think that's 1 1/2 cups.
