It depends how many grams are in the cup. If you know this then just half it and that is the answer. If you don't then well I'm not sure how to do it.
You can convert 300 g of icing sugar into ounces or cups. 300 grams of icing sugar is equal to 12 ounces or 2.4 cups.
Icing sugar is about 160 grams per cup. So that is about 2 cups.
One official cup is 250gm. So your amount is approximately 1/5 of a cup.
Icing sugar is not normally measured by the ml, since mls are designed for liquids only. ( Measuring icing sugar by the mil is highly inadvisable due to the large potential for inaccuracies.) It would be best to find a weight measurement for icing sugar to convert to cups, if the measurement must be in cups.
One and a quarter cups hope this helps.
One cup is 250 gm. -So 500 gm is about 2 cups.
