220 Grams of Cornstarch in Cups
220 grams of cornstarch doesn't land on a clean fraction, so the result below is calculated exactly rather than rounded to a common measure. Based on a density of 128g per cup, it equals 1.72 cups.

220 grams of cornstarch = 1.72 cups (1¾ cup / 27.5 tbsp / 82.5 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 |
|---|---|---|---|---|
| 200g | 1.56 | 1½ | 25.0 | 75.0 |
| 210g | 1.64 | 1⅝ | 26.3 | 78.8 |
| 220g | 1.72 | 1¾ | 27.5 | 82.5 |
| 225g | 1.76 | 1¾ | 28.1 | 84.4 |
| 230g | 1.80 | 1¾ | 28.8 | 86.3 |
How 220g Converts, Step by Step
220g divided by 128g (the weight of one cup of cornstarch) equals 1.72 cups. Multiplying that by 16 gives 27.5 tablespoons, and by 48 gives 82.5 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 220g of cornstarch takes up more volume (407ml) than the same weight of water would (221ml). For a side-by-side look at how other ingredients compare, see the 220 grams to cups page.
If You're Using a Metric or Imperial Cup
The 1.72 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 220g, that's 1⅝ metric cups or 1⅜ 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 This 220g Amount
Doubling a recipe that calls for 220g of cornstarch means weighing 440g, or measuring 3.44 cups if you're working by volume instead of weight. Halving it means 110g, or 0.86 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 Next to Other Dry Goods
Within dry goods, density still varies by ingredient. At 220g, protein powder (120g per cup) measures 1⅞ cups, while rolled oats (90g per cup) measures 2½ cups, compared to 1¾ cup for cornstarch. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where This Amount Shows Up in Recipes
- 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.
Measuring This Precisely
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 220 grams of cornstarch in cups exactly?+
220 grams of cornstarch equals 1.72 cups, based on a density of 128g per cup.
Why doesn't 220g of cornstarch match a simple fraction?+
220g isn't a multiple of cornstarch's per-cup weight, so the cup value lands between common fractions. The closest practical measure is 1¾ cup.
What's the most reliable way to measure 220g of cornstarch?+
A kitchen scale set to grams gives an exact 220g reading. Cups only approximate this amount, since 1¾ cup rounds to the nearest practical fraction.
Is 220g likely a typo for a rounder amount?+
Possibly, if a recipe seems to expect a cleaner number. Check the nearby amounts table below for the closest common gram values for cornstarch.
