400 grams of quinoa = 2.35 cups (2⅓ cups / 37.6 tbsp / 112.9 tsp)
Quinoa has a density of approximately 170g per cup. Uncooked, dry quinoa. Cooked quinoa weighs closer to 185g per cup. 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 |
|---|---|---|---|---|
| 350g | 2.06 | 2⅛ | 32.9 | 98.8 |
| 375g | 2.21 | 2¼ | 35.3 | 105.9 |
| 400g | 2.35 | 2⅓ | 37.6 | 112.9 |
| 425g | 2.50 | 2½ | 40.0 | 120.0 |
| 450g | 2.65 | 2⅔ | 42.4 | 127.1 |
How the 400g Figure Is Calculated
400g divided by 170g (the weight of one cup of quinoa) equals 2.35 cups. Multiplying that by 16 gives 37.6 tablespoons, and by 48 gives 112.9 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Quinoa is lighter than water, which weighs about 236g per cup. That's why 400g of quinoa takes up more volume (557ml) than the same weight of water would (401ml). For a side-by-side look at how other ingredients compare, see the 400 grams to cups page.
If Your Recipe Uses Metric or Imperial Cups
The 2.35 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 400g, that's 2¼ metric cups or 1⅞ imperial cups of quinoa, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling 400g Up or Down
Doubling a recipe that calls for 400g of quinoa means weighing 800g, or measuring 4.71 cups if you're working by volume instead of weight. Halving it means 200g, or 1.18 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.
Quinoa vs. Other Grains & Pasta
Within grains & pasta, density still varies by ingredient. At 400g, white rice (185g per cup) measures 2⅛ cups, compared to 2⅓ cups for quinoa. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where 400g of Quinoa Fits in a Recipe
- A single serving of quinoa is typically 45g to 60g uncooked.
- Quinoa salad recipes often call for 170g (1 cup) uncooked to serve four.
- Breakfast quinoa bowls usually need about 50g per serving.
How to Measure It Accurately
Grains & Pasta
Spoon into the cup and level off. Avoid pressing down, since grains and pasta shapes settle differently than powders.
For exact results
Rice and grains can vary in density based on how long they've been stored, since older, drier grains pack slightly more densely into the same cup than fresher ones.

Why is quinoa's gram-to-cup ratio different from other ingredients?+
Quinoa weighs 170g per cup because of its own density. Uncooked, dry quinoa. Cooked quinoa weighs closer to 185g per cup.
Does a metric or imperial cup change this 400g conversion?+
Yes, slightly. 400g of quinoa is 2¼ metric cups or 1⅞ imperial cups, versus 2⅓ US cups, since each cup standard holds a different volume.
