230g is equal to how many cups?

28 grams is approximately equal to 1 ounce (0.9877 to be precise). Therefore it would be a little bit less than 1/8 of a cup (0.1234625 cup to be precise).

All of the above is correct if you're talking about distilled water. Otherwise, the question is not answerable. Grams are a measure of mass (weight) and cups are a measure of volume. You cannot convert from mass to volume without knowing what the item is. 28g of sugar would be much less than a cup, and 28 g of marshmallows would be quite a bit more.
