How to convert cups of cornstarch to grams

One level US cup of cornstarch weighs about 120 g. Multiply: 1/8 × 120 = 15 g.

Spoon flour into the cup and level it with a knife. Scooping straight from the bag packs it down and can add 20–30% more.

Frequently asked questions

How many grams is 1/8 cup of cornstarch?

1/8 cup of cornstarch is 15 grams, based on 120 g per level US cup.

Is it different with a UK or Australian cup?

Slightly. UK, Australian and New Zealand recipes use a 250 ml metric cup, which is about 6% bigger than a US cup (236.6 ml). Using a metric cup, 1/8 cup of cornstarch would be 16 g.

Should I weigh cornstarch or measure it by volume?

Spoon flour into the cup and level it with a knife. Scooping straight from the bag packs it down and can add 20–30% more. Weighing is always more accurate, which is why grams are the safest choice for baking.
