Grams of uncooked quinoa to millilitres runs on one number, 1.3916955 millilitres per gram. 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
grams- The amount of uncooked quinoa you are converting, in grams
1.39169550882- Millilitres per gram for uncooked quinoa, from its density of 0.71855 g/mL
millilitres- The equivalent quantity in millilitres
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 1.39169550882, the millilitres-per-gram figure for uncooked quinoa.
- The result appears in millilitres, with a second reading in tsp beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
50 g of uncooked quinoa in millilitres
A recipe calling for 50 g of uncooked quinoa needs 69.5848 millilitres on the scale. The arithmetic is 50 × 1.3916955 = 69.584775, and halving the recipe halves the weight to 34.7924 millilitres.
150 g of uncooked quinoa in millilitres
Take 150 g of uncooked quinoa: 150 × 1.3916955 gives 208.754 millilitres. Doubling the batch takes it to 417.509 millilitres, because the relationship is a straight proportion once the density is known.
500 g of uncooked quinoa in millilitres
A recipe calling for 500 g of uncooked quinoa needs 695.848 millilitres on the scale. The arithmetic is 500 × 1.3916955 = 695.84775, and halving the recipe halves the weight to 347.924 millilitres.

Frequently asked questions
How many millilitres are in 1 g of uncooked quinoa?
One gram of uncooked quinoa is 1.3916955 millilitres. Half that quantity is 0.695848 millilitres and double it is 2.78339 millilitres, 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 much does 15 mL of uncooked quinoa weigh?
15 mL of uncooked quinoa comes to 10.778 g, or 10.778 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the ml-to-grams page does it in the direction the question is usually asked.
