Why is cornstarch published per quarter cup?
Because that is nearer the amount a recipe asks for. King Arthur lists cornstarch at 28 g per quarter cup; four of those make the 112 g per cup that dishscale converts from. The arithmetic is exact, so a quarter cup still reads 28 g when you convert back.

Frequently asked questions
How many grams is 4 oz of Cornstarch?
4 oz of Cornstarch is 113.4 grams. Grams and ounces are both weights, so this one does not depend on the ingredient at all — one ounce is 28.3495 grams for Cornstarch as for everything else. The ingredient starts to matter the moment one side is a volume: a cup of Cornstarch weighs 112 g.
How many oz is 100 grams of Cornstarch?
100 grams of Cornstarch is 3.53 oz. It is the same conversion read backwards, so this page and its reverse always agree.
Is that ounces by weight, or fluid ounces?
By weight. dishscale's ounce is the international avoirdupois ounce, 28.3495 g, so one cup of Cornstarch is 3.95 oz. A US fluid ounce is a volume and there are eight of them to the cup, so that same cup is 8 fl oz at the same time. The two readings coincide only for an ingredient that happens to weigh eight ounces to the cup.
