One gram of dry couscous is 0.28235294 teaspoons, so converting grams of dry couscous to teaspoons means multiplying by 0.28235294. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
Water is the yardstick: 1 mL of it weighs 1 g. Dry couscous comes in at 0.71855 g per mL, or 71.85% of water, which is why a cup of it is 170 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
A level teaspoon of dry couscous weighs 3.542 g. A kitchen scale that reads to the nearest gram is therefore working at roughly 28.2% resolution on a single spoonful, which is why measuring spoons beat scales below about 5 g and lose to them above it. Three teaspoons make a tablespoon, so the same spoonful is 10.62 g if the recipe scales up.
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
grams- The amount of dry couscous you are converting, in grams
0.282352941176- Teaspoons per gram for dry couscous, from its density of 0.71855 g/mL
teaspoons- The equivalent quantity in teaspoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.282352941176, the teaspoons-per-gram figure for dry couscous.
- The result appears in teaspoons, with a second reading in mL 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 dry couscous in teaspoons
Take 50 g of dry couscous: 50 × 0.28235294 gives 14.1176 teaspoons. Doubling the batch takes it to 28.2353 teaspoons, because the relationship is a straight proportion once the density is known.
150 g of dry couscous in teaspoons
150 g of dry couscous weighs out at 42.3529 teaspoons. Divide 42.3529 by 0.28235294 and you get back to 150 g, which is the quickest check that the factor is the right way up.
500 g of dry couscous in teaspoons
A recipe calling for 500 g of dry couscous needs 141.176 teaspoons on the scale. The arithmetic is 500 × 0.28235294 = 141.17647, and halving the recipe halves the weight to 70.5882 teaspoons.

Frequently asked questions
How many teaspoons are in 1 g of dry couscous?
One gram of dry couscous is 0.28235294 teaspoons. Half that quantity is 0.141176 teaspoons and double it is 0.564706 teaspoons, 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?
At this size the spoon wins. One teaspoon of dry couscous is 3.542 g, and a scale reading to the nearest gram is working at 28.2% 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 2 tsp of dry couscous weigh?
2 tsp of dry couscous comes to 7.0833 g, or 7.0833 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the teaspoons-to-grams page does it in the direction the question is usually asked.
