To convert cups of dry couscous into ounces, multiply by 5.9965735: one cup comes to 5.9965735 ounces. Every ingredient has its own figure here, because the units are measuring different things and only the density links them.
Put next to water — 1 g per mL exactly — dry couscous measures 0.71855 g per mL. That ratio, 71.85%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
A cup of dry couscous is 170 g when it is measured the standard way, but how it gets into the cup changes the answer: between about 153 g and 204 g covers the range from lightly spooned to firmly packed. That 20% spread is larger than most of the adjustments recipes fuss over, and it disappears entirely the moment the ingredient is weighed instead.
One cup of dry couscous is 5.997 oz. US kitchen scales usually step in eighths of an ounce, which is 3.54 g — around 2.08% of a cup of this ingredient, so the scale is precise enough for a full cup and coarse for a spoonful. That is why recipes mix the two systems: ounces for the bulk, spoons for the small amounts.
The condition this weight assumes: Before steaming. It roughly triples in volume once hydrated, which is why the dry weight is the useful one.
The formula
cups- The amount of dry couscous you are converting, in cups
5.99657353143- Ounces per cup for dry couscous, from its density of 0.71855 g/mL
ounces- The equivalent quantity in ounces
How it works, step by step
- Enter the quantity in cups.
- It is multiplied by 5.99657353143, the ounces-per-cup figure for dry couscous.
- The result appears in ounces, with a second reading in g beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
1/3 cup of dry couscous in ounces
A recipe calling for 1/3 cup of dry couscous needs 1.99886 ounces on the scale. The arithmetic is 0.333333 × 5.9965735 = 1.9988578, and halving the recipe halves the weight to 0.999429 ounces.
3/4 cup of dry couscous in ounces
3/4 cup of dry couscous weighs out at 4.49743 ounces. Divide 4.49743 by 5.9965735 and you get back to 3/4 cup, which is the quickest check that the factor is the right way up.
3 cup of dry couscous in ounces
A recipe calling for 3 cup of dry couscous needs 17.9897 ounces on the scale. The arithmetic is 3 × 5.9965735 = 17.989721, and halving the recipe halves the weight to 8.99486 ounces.

Frequently asked questions
How many ounces are in 1 cup of dry couscous?
One cup of dry couscous is 5.9965735 ounces. Half that quantity is 2.99829 ounces and double it is 11.9931 ounces, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of dry couscous not 236 g like water?
Because weight per cup depends on what is in the cup. Dry couscous 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 dry couscous by roughly 20% — about 17 g either side of 170 g — because before steaming. Weighing removes the question entirely.
Is a fluid ounce of dry couscous 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 dry couscous 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 dry couscous 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?
A scale, if the result matters. Volume measuring carries a spread of about 20% for dry couscous — roughly 34 g on a 170 g cup — while a domestic scale is accurate to a gram or two. For anything where the ratio of ingredients drives the outcome, bread and pastry above all, weigh it.
How many cups of dry couscous is 16 oz?
16 oz of dry couscous is 2.6682 cups — 0.166762 cups to one ounce, so 16 × 0.166762 = 2.6682. Going that way is a division by 5.99657, or a multiplication by 0.166762 if you prefer.
