45 Grams of Quinoa in Cups
45 grams of quinoa 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 170g per cup, it equals 0.26 cups.

45 grams of quinoa = 0.26 cups (¼ cup / 4.2 tbsp / 12.7 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 |
|---|---|---|---|---|
| 35g | 0.21 | ¼ | 3.3 | 9.9 |
| 40g | 0.24 | ¼ | 3.8 | 11.3 |
| 45g | 0.26 | ¼ | 4.2 | 12.7 |
| 50g | 0.29 | ⅓ | 4.7 | 14.1 |
| 55g | 0.32 | ⅓ | 5.2 | 15.5 |
How 45g Converts, Step by Step
45g divided by 170g (the weight of one cup of quinoa) equals 0.26 cups. Multiplying that by 16 gives 4.2 tablespoons, and by 48 gives 12.7 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 45g of quinoa takes up more volume (63ml) than the same weight of water would (45ml). For a side-by-side look at how other ingredients compare, see the 45 grams to cups page.
If You're Using a Metric or Imperial Cup
The 0.26 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 45g, that's ¼ metric cups or ¼ 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 This 45g Amount
Doubling a recipe that calls for 45g of quinoa means weighing 90g, or measuring 0.53 cups if you're working by volume instead of weight. Halving it means 22.5g, or 0.13 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 Next to Other Grains & Pasta
Within grains & pasta, density still varies by ingredient. At 45g, white rice (185g per cup) measures ¼ cup, compared to ¼ cup for quinoa. 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
- 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.
Measuring This Precisely
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 45 grams of quinoa in cups exactly?+
45 grams of quinoa equals 0.26 cups, based on a density of 170g per cup.
Why doesn't 45g of quinoa match a simple fraction?+
45g isn't a multiple of quinoa's per-cup weight, so the cup value lands between common fractions. The closest practical measure is ¼ cup.
What's the most reliable way to measure 45g of quinoa?+
A kitchen scale set to grams gives an exact 45g reading. Cups only approximate this amount, since ¼ cup rounds to the nearest practical fraction.
Is 45g 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 quinoa.
