2 cups of quinoa weighs 354 g (approximately, spooned and levelled, King Arthur Baking). That is the short answer, and it is the number to use when a recipe calls for two cups and your scale is the tool you trust. One cup weighs 177 g, so two cups is simply double that — 177 g × 2 = 354 g. Tiny gluten-free seeds cooked like a grain. It is used for salads, bowls, pilaf and breakfast porridge. This page gives you the full conversion table for quinoa, three worked examples from real recipes, and the measuring method behind the number, so you can use it with confidence whether you are doubling a favourite recipe or scaling a batch for a crowd.
Conversion table: cups of quinoa to grams
The table below covers the amounts you will actually reach for, from a quarter cup to three cups. Every figure is 177 g per cup multiplied by the amount, rounded to the nearest gram, and every figure is approximate. The two-cup row is the one this page is named for, but the quarter, third and half-cup rows are the ones you will use when a recipe needs adjusting rather than doubling.
| Cups | Grams (approx.) |
|---|---|
| 1/4 cup | 44 g |
| 1/3 cup | 59 g |
| 1/2 cup | 88 g |
| 2/3 cup | 118 g |
| 3/4 cup | 133 g |
| 1 cup | 177 g |
| 1 1/4 cups | 221 g |
| 1 1/2 cups | 266 g |
| 1 3/4 cups | 310 g |
| 2 cups | 354 g |
| 2 1/2 cups | 442 g |
| 3 cups | 531 g |
A useful check on the table: one tablespoon of quinoa weighs about 11.1 g, because there are 16 tablespoons in a cup and 177 ÷ 16 = 11.1. That means 2 cups is 32 tablespoons, and if you only need a spoonful or two of adjustment, the tablespoon figure is the one to use. It also explains why recipes written in tablespoons and recipes written in cups can disagree slightly — a tablespoon is a small measure and small errors multiply across 32 spoonfuls, which is another reason to weigh the full amount when you can.
Worked examples: 2 cups of quinoa in real recipes
Example 1 — doubling a recipe that calls for 1 cup
A recipe for a tray of bakes calls for 1 cup of quinoa, which is 177 g. You want a double batch for a gathering, so you need 2 cups. Double the weight: 177 g × 2 = 354 g. Weigh 354 g into the bowl and you have doubled the ingredient exactly, without the packing error that two scooped cups would have introduced. Remember to double the raising agents and the liquid by the same proportion, and use a larger tin — a doubled batter in the original tin overflows or bakes unevenly.
Example 2 — a recipe that already calls for 2 cups
Some recipes are written around two cups from the start — a large batch of a bake that uses quinoa among its main ingredients (salads, bowls, pilaf and breakfast porridge). Weigh 354 g, spooned and levelled, and add it in the order the recipe specifies. If the recipe also lists other ingredients in cups, weigh those too rather than mixing weighed and scooped measures: a recipe is only as accurate as its least accurate ingredient, and mixing methods is how a good batter turns out heavy.
Example 3 — halving the two-cup amount
Going the other way, suppose you only want half the batch. Half of 2 cups is 1 cup, which is 177 g, and half of that again is 1/2 cup at 88 g. Weighing makes halving trivial in a way scooping never is, because a half cup of a light, airy ingredient is hard to judge by eye. Weigh 177 g, halve the remaining ingredients in the same proportion, and expect a slightly shorter baking time in the smaller tin.
How the cup was measured (and why it matters)
Every figure on this page assumes the cup was spooned and levelled. That phrase is doing real work: for quinoa, the difference between a spooned cup and a scooped cup can be 10 to 20 percent, which is far more than any rounding in the table. To measure spooned and levelled, use a dry measuring cup (not a liquid jug), fill it without packing unless the method says packed, and level it off with the back of a knife. For poured ingredients, use a liquid measuring jug at eye level. The source for the 177 g per cup figure is King Arthur Baking, and the confidence in the figure is high. There is no famous dispute about the weight of quinoa: the figure used here is stable across the sources we checked, which is one reason this conversion is reliable. Even so, every figure on this page is labelled approximate, because how full the cup is, how settled the ingredient is, and the temperature in your kitchen all move the number a little. When precision matters, verify with a kitchen scale.
When the conversion matters most
The conversion matters most where quinoa does structural work. In baking, too much of a dry ingredient makes a crumb dry and dense, while too little makes it collapse; too much of a wet one makes a batter slack and slow to set. For salads, bowls, pilaf and breakfast porridge. the stakes are real but not mysterious: weigh the ingredient, follow the recipe's order, and check the batter's look before it goes in the oven. A batter that looks right is usually right, and weighing is what makes it look right the first time. Storage matters too: Airtight container, cool and dry, up to 1 year.
Scaling the recipe up or down
Two cups is rarely the only amount a recipe needs, so here is how the number scales. A half batch needs 1 cup, which is 177 g. A quarter batch needs 1/2 cup, which is 88 g. A triple batch needs 6 cups, which is 1,062 g. And one and a half times the recipe needs 3 cups, which is 531 g. The pattern is the same every time — multiply 177 g by the cups — but the practicalities change with size. Small batches are forgiving: a few grams either way will not show. Large batches are not: a 10 g error in a single cake becomes a 30 g error across a triple batch, and the tin, the mixing bowl and the baking time all have to grow with it. A triple batch needs a bowl with real headroom, a tin (or two tins) with roughly three times the volume, and a bake that you check early, because the outside browns before the middle sets. Scale the raising agents and the salt by the same factor as everything else — the commonest scaling mistake is scaling the bulk ingredients and forgetting the small ones. Weigh each scaled amount rather than converting in your head, and write the scaled numbers down before you start: a recipe scaled on paper is a recipe you can repeat, while a recipe scaled from memory is a recipe you will have to guess at again next time.
Frequently asked questions
How many grams is 2 cups of quinoa?
2 cups of quinoa weighs approximately 354 g. One cup is 177 g (spooned and levelled, King Arthur Baking), so the calculation is 177 × 2 = 354 g. The figure is approximate: how you fill the cup moves the weight, so verify with a kitchen scale when precision matters.
How many tablespoons are in 2 cups of quinoa?
There are 32 tablespoons in 2 cups, and one tablespoon of quinoa weighs about 11.1 g (177 g per cup ÷ 16). Spoonfuls are useful for small adjustments, but for the full two cups, weighing the 354 g directly is more accurate than counting 32 spoonfuls.
Can I measure 2 cups of quinoa without a scale?
Yes — use a dry measuring cup, spoon the quinoa in loosely, and level it off with the back of a knife. Do not scoop with the cup itself and do not pack it unless the method says packed. Two careful cups will land close to 354 g, which is good enough for everyday cooking, though a scale is better for baking.
Why do different websites give different weights for quinoa?
Because they measure the cup differently. King Arthur Baking lists 177 g per cup spooned and levelled, while other sources may scoop, sift or pack, and each method gives a different weight. The ingredient itself has not changed — only the measuring method has. Match the method and the numbers agree.
Is it better to weigh or to measure quinoa in cups?
Weighing is better whenever the recipe is a bake or a batch you want to repeat, because a scale reads the same every time while a cup varies with how you fill it. For soups, sauces and weekday cooking, a careful cup measure is usually fine. The threshold is the recipe: if the result depends on the ratio, weigh it.
What if my recipe calls for 2 cups but I only have a partial bag?
Weigh what you have. If the bag holds 266 g, that is 1 1/2 cups, and you can scale the whole recipe down by a quarter — multiply every other ingredient by 0.75. Weighing makes that rescue possible; guessing by eye does not.
