One tablespoon of dry couscous is 10.625 grams, so converting tablespoons of dry couscous to grams means multiplying by 10.625. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
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 level tablespoon of dry couscous is 10.62 g, which puts a teaspoon at 3.542 g and a tablespoon and a half — the quantity recipes are fondest of — at 15.94 g. Levelling twice is where the error comes from, so the scale is the faster instrument once the quantity passes a couple of spoons.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.588% of a cup of dry couscous, 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: Before steaming. It roughly triples in volume once hydrated, which is why the dry weight is the useful one.
The formula
tablespoons- The amount of dry couscous you are converting, in tablespoons
10.625- Grams per tablespoon for dry couscous, from its density of 0.71855 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in tablespoons.
- It is multiplied by 10.625, the grams-per-tablespoon figure for dry couscous.
- 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
2 tbsp of dry couscous in grams
A recipe calling for 2 tbsp of dry couscous needs 21.25 grams on the scale. The arithmetic is 2 × 10.625 = 21.25, and halving the recipe halves the weight to 10.625 grams.
4 tbsp of dry couscous in grams
4 tbsp of dry couscous weighs out at 42.5 grams. Divide 42.5 by 10.625 and you get back to 4 tbsp, which is the quickest check that the factor is the right way up.
12 tbsp of dry couscous in grams
A recipe calling for 12 tbsp of dry couscous needs 127.5 grams on the scale. The arithmetic is 12 × 10.625 = 127.5, and halving the recipe halves the weight to 63.75 grams.

Frequently asked questions
How many grams are in 1 tbsp of dry couscous?
One tablespoon of dry couscous is 10.625 grams. Half that quantity is 5.3125 grams and double it is 21.25 grams, 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 tablespoons of dry couscous is 500 g?
500 g of dry couscous is 47.059 tablespoons — 0.0941176 tablespoons to one gram, so 500 × 0.0941176 = 47.059. Going that way is a division by 10.625, or a multiplication by 0.0941176 if you prefer.
