Millilitres of uncooked quinoa to grams runs on one number, 0.71854798 grams per millilitre. It is a measured property of this ingredient rather than a defined conversion, which is why a generic volume-to-weight tool cannot give you it.
The density behind that figure is 0.71855 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of uncooked quinoa weighs 170 g, so this ingredient is 71.85% as heavy as the same volume of water — the single fact the whole page rests on.
Uncooked quinoa has a density of 0.71855 g per mL, so 100 mL of it weighs 71.85 g and 250 mL weighs 179.6 g. That single figure is what every other number on this page is built from — water is 1.00 g per mL, so this ingredient is 71.85% as heavy as the same volume of water.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.588% of a cup of uncooked quinoa, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 2.941 cups, and a 1 kg pack 5.882.
The condition this weight assumes: Dry and rinsed. The seeds are small and round, so they pack closely.
The formula
millilitres- The amount of uncooked quinoa you are converting, in millilitres
0.718547982414- Grams per millilitre for uncooked quinoa, from its density of 0.71855 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in millilitres.
- It is multiplied by 0.718547982414, the grams-per-millilitre figure for uncooked quinoa.
- The result appears in grams, with a second reading in oz beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
15 mL of uncooked quinoa in grams
A recipe calling for 15 mL of uncooked quinoa needs 10.7782 grams on the scale. The arithmetic is 15 × 0.71854798 = 10.77822, and halving the recipe halves the weight to 5.38911 grams.
100 mL of uncooked quinoa in grams
100 mL of uncooked quinoa weighs out at 71.8548 grams. Divide 71.8548 by 0.71854798 and you get back to 100 mL, which is the quickest check that the factor is the right way up.
250 mL of uncooked quinoa in grams
A recipe calling for 250 mL of uncooked quinoa needs 179.637 grams on the scale. The arithmetic is 250 × 0.71854798 = 179.637, and halving the recipe halves the weight to 89.8185 grams.

Frequently asked questions
How many grams are in 1 mL of uncooked quinoa?
One millilitre of uncooked quinoa is 0.71854798 grams. Half that quantity is 0.359274 grams and double it is 1.4371 grams, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of uncooked quinoa not 236 g like water?
Because weight per cup depends on what is in the cup. Uncooked quinoa has a density of 0.71855 g per mL where water has 1.00, so a cup of it weighs 170 g rather than 236.6 g. That is a difference of 66.6 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Yes, and by more than most people expect. Handling changes the weight of a cup of uncooked quinoa by roughly 20% — about 17 g either side of 170 g — because dry and rinsed. Weighing removes the question entirely.
Is a fluid ounce of uncooked quinoa the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of uncooked quinoa weighs 0.7496 oz, so the two readings differ by 25%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of uncooked quinoa would weigh 179.64 g instead of 170 g — 9.64 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
At this size the spoon wins. One millilitre of uncooked quinoa is 0.7185 g, and a scale reading to the nearest gram is working at 139% resolution on that — a measuring spoon is the more accurate instrument below about 5 g, which is why spice quantities are still written in spoons.
How many millilitres of uncooked quinoa is 500 g?
500 g of uncooked quinoa is 695.85 millilitres — 1.3917 millilitres to one gram, so 500 × 1.3917 = 695.85. Going that way is a division by 0.718548, or a multiplication by 1.3917 if you prefer.
