How many grams is 3 1/3 cups of cornstarch?
Answer
One US cup (236.6 ml) of cornstarch weighs 128 grams, from USDA FoodData Central, SR Legacy entry 169698 “Cornstarch”, portion “1 cup” = 128 grams.
3 1/3 cups of cornstarch equals 426.7 grams; the way back, from grams to cups, is the Grams to Cups converter.
This is the US customary cup of 236.6 ml. A recipe written for the metric cup of 250 ml (Australia, New Zealand, Canada) means 5.7 % more: 450.9 grams.
How 3 1/3 cups of cornstarch was converted to grams
One US cup of cornstarch weighs 128 grams (one hundred twenty-eight), so multiply 3 1/3 by 128.
3 1/3 × 128 g
≈426.7 grams
(four hundred twenty-six point seven grams)
The weight of the cup comes from USDA FoodData Central, SR Legacy entry 169698 “Cornstarch”, portion “1 cup” = 128 grams. Scooped ingredients vary with how they are filled — spooned in lightly, a cup weighs less; packed down, more — so for baking a kitchen scale is the exact tool and this figure the standard reference.

The other way round: how many cups a weight fills
This page starts from cups and answers in grams. The opposite question — how many cups a weight from a recipe fills — is what the grams to cups converter is for. Both read the same USDA weights, so their numbers agree: 100 grams of cornstarch is 0.78 cups there.
