200 grams of cornstarch = 1.56 cups (1½ cup / 25.0 tbsp / 75.0 tsp)
Cornstarch has a density of approximately 128g per cup. Sifted cornstarch is closer to 115g. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.
| Grams | Cups | Fraction | Tablespoons | Teaspoons |
|---|---|---|---|---|
| 180g | 1.41 | 1⅜ | 22.5 | 67.5 |
| 190g | 1.48 | 1½ | 23.8 | 71.3 |
| 200g | 1.56 | 1½ | 25.0 | 75.0 |
| 210g | 1.64 | 1⅝ | 26.3 | 78.8 |
| 220g | 1.72 | 1¾ | 27.5 | 82.5 |
How the 200g Figure Is Calculated
200g divided by 128g (the weight of one cup of cornstarch) equals 1.56 cups. Multiplying that by 16 gives 25.0 tablespoons, and by 48 gives 75.0 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Cornstarch is lighter than water, which weighs about 236g per cup. That's why 200g of cornstarch takes up more volume (370ml) than the same weight of water would (200ml). For a side-by-side look at how other ingredients compare, see the 200 grams to cups page.
If Your Recipe Uses Metric or Imperial Cups
The 1.56 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 200g, that's 1½ metric cups or 1⅓ imperial cups of cornstarch, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling 200g Up or Down
Doubling a recipe that calls for 200g of cornstarch means weighing 400g, or measuring 3.13 cups if you're working by volume instead of weight. Halving it means 100g, or 0.78 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.
Cornstarch vs. Other Dry Goods
Within dry goods, density still varies by ingredient. At 200g, protein powder (120g per cup) measures 1⅔ cup, while rolled oats (90g per cup) measures 2¼ cups, compared to 1½ cup for cornstarch. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where 200g of Cornstarch Fits in a Recipe
- Fruit pie fillings typically use 20g to 30g of cornstarch as a thickener.
- Stir-fry sauces often call for 10g mixed with water as a slurry.
- Custards and puddings usually need 15g to 25g per batch.
How to Measure It Accurately
Dry Goods
Spoon into the cup and level off. Ingredients like cocoa powder benefit from a quick sift first to break up clumps.
For exact results
Baking soda and baking powder should always be measured with a dry measuring spoon, leveled flat — a heaping spoonful of either can meaningfully change how a baked good rises.

Frequently Asked Questions
What is 200 grams of cornstarch in cups?+
200 grams of cornstarch is 1.56 cups (1½ cup), or 25.0 tablespoons.
How do I measure 200 grams of cornstarch without a scale?+
Use 1½ cup, spooned in and leveled off with a straight edge. If you only have tablespoons, use 25.0 tablespoons instead.
Why is cornstarch's gram-to-cup ratio different from other ingredients?+
Cornstarch weighs 128g per cup because of its own density. Sifted cornstarch is closer to 115g.
Does a metric or imperial cup change this 200g conversion?+
Yes, slightly. 200g of cornstarch is 1½ metric cups or 1⅓ imperial cups, versus 1½ US cups, since each cup standard holds a different volume.
