15g Quinoa to Cups
15 grams of quinoa is a small amount, best measured with a spoon rather than a full cup. At 170g per cup, it works out to 1.4 tablespoons.

15 grams of quinoa = 0.09 cups (⅛ cup / 1.4 tbsp / 4.2 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 |
|---|---|---|---|---|
| 9g | 0.05 | ⅛ | 0.8 | 2.5 |
| 10g | 0.06 | ⅛ | 0.9 | 2.8 |
| 15g | 0.09 | ⅛ | 1.4 | 4.2 |
| 20g | 0.12 | ⅛ | 1.9 | 5.6 |
| 25g | 0.15 | ⅛ | 2.4 | 7.1 |
The Math for 15g of Quinoa
15g divided by 170g (the weight of one cup of quinoa) equals 0.09 cups. Multiplying that by 16 gives 1.4 tablespoons, and by 48 gives 4.2 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 15g of quinoa takes up more volume (21ml) than the same weight of water would (15ml). For a side-by-side look at how other ingredients compare, see the 15 grams to cups page.
Metric and Imperial Cup Sizes
The 0.09 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 15g, that's ⅛ metric cups or ⅛ 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.
Making More or Less Than 15g
Doubling a recipe that calls for 15g of quinoa means weighing 30g, or measuring 0.18 cups if you're working by volume instead of weight. Halving it means 7.5g, or 0.04 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.
How Quinoa Compares to Similar Ingredients
Within grains & pasta, density still varies by ingredient. At 15g, white rice (185g per cup) measures ⅛ cup, compared to ⅛ cup for quinoa. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Typical Uses for Quinoa
- 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.
Getting an Accurate Spoon Measurement
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.

Frequently Asked Questions
What is 15 grams of quinoa in cups?+
15 grams of quinoa is 0.09 cups, or 1.4 tablespoons.
Should I use a spoon or a cup for 15g of quinoa?+
At 15g, a tablespoon or teaspoon measurement is usually more practical than a fractional cup. Use 1.4 tablespoons or 4.2 teaspoons.
Is 15 grams of quinoa the same as 15 milliliters?+
Only if it weighed the same as water. 15g of water is about 15ml, while 15g of quinoa is 21ml, because the two have different densities.
Does the answer change for a metric or imperial cup?+
Slightly. 15g of quinoa is ⅛ metric cups or ⅛ imperial cups, close to the US figure but not identical, since each standard defines the cup at a different volume.
