| Measure | Grams |
|---|---|
| 1 metric cup (250 ml) | 118 g |
| ½ metric cup | 59 g |
| 1 UK/metric tablespoon (15 ml) | 7.1 g |
| 1 Australian tablespoon (20 ml) | 9.5 g |
| 100 ml | 47 g |
A metric cup (250 ml, used in Australia, New Zealand, Canada and many Indian recipes) holds about 6% more than a US cup.
Spoon the flour into the cup and level it with a knife. Scooping straight from the bag packs it down and can add 20–30% more.
In the UK and India "cornflour" means this fine white starch, not cornmeal.
Also called: cornflour (UK, India).
Weights are for a level US cup (236.6 ml) and level spoons, from King Arthur Baking's ingredient weight chart. Brands and packing vary by a few per cent; when a recipe gives grams, weigh rather than measure.
1 level US cup of cornstarch weighs about 112 g (4 oz). A 250 ml metric cup weighs about 118 g.
1 level tablespoon of cornstarch is about 7 g, and 1 teaspoon is about 2.3 g.
100 g of cornstarch is about 0.89 cups, or 14.3 tablespoons.
A cup measures volume, not weight. Cornstarch is full of air between the particles, so a cup weighs much less than a cup of water (112 g vs 237 g).
