One cup, side by side
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 ml is 100 grams of Cornstarch?
100 grams of Cornstarch is 211.2 ml, because one US cup of Cornstarch weighs 112 g. That single measured figure is the whole conversion — every other unit on this page is derived from it.
How many grams is 250 ml of Cornstarch?
250 ml of Cornstarch is 118.3 grams. It is the same conversion read backwards, so this page and its reverse always agree.
Is one millilitre of Cornstarch the same as one gram?
No — that holds for water alone. Cornstarch works out at 0.473 g/ml, so 100 ml of it weighs 47.34 g rather than 100 g. A converter that assumes a millilitre is a gram is really only telling you about water.
Where does dishscale's figure for Cornstarch come from?
One US cup of Cornstarch is 112 g. The dataset records that as: “King Arthur Baking (28 g per 1/4 cup)”. That is the King Arthur Baking ingredient weight chart. Every ingredient on the site carries the reference its weight came from, so any number here can be checked — and corrected if the source disagrees.
