Fenugreek Seeds: Teaspoon to Grams Conversion
Exact weight conversions for whole fenugreek seeds and ground powder — teaspoons, tablespoons, cups and grams. Live converter + quick-reference chart. Looking for how much to actually take? See our fenugreek dosage guide.
Common kitchen rounding: 1 tsp whole seeds ≈ 5g · 1 tsp powder ≈ 3.75g · 1 tbsp seeds ≈ 15g · USDA lab-measured: 1 tsp whole seeds ≈ 3.7g · 1 tbsp ≈ 11g · 1 cup ≈ 188g — see below for which one to use.
- 1 level teaspoon of whole fenugreek seeds = about 5 grams (common kitchen rounding) or about 3.7 grams (USDA lab-measured density).
- 1 level teaspoon of ground fenugreek powder = about 3.5–4 grams (kitchen) or about 2.5 grams (USDA).
- 1 level tablespoon of whole seeds = 3 teaspoons = approximately 15 grams (kitchen) or 11 grams (USDA).
- 1 cup of whole fenugreek seeds weighs approximately 240 grams (kitchen) or 188 grams (USDA).
- Whole seeds and ground powder are not the same weight per teaspoon — powder is denser by volume than intact seeds.
- Kasuri methi (dried fenugreek leaves) is a different ingredient from fenugreek seeds and is never interchangeable gram-for-gram.
- For a precise dose rather than a recipe, weigh on a digital kitchen scale rather than relying on spoon measurements.

Master Conversion Table — Seeds & Powder
Weights below are for level (not heaped) measures at room temperature. A heaped spoon can add 15–20% more weight — for therapeutic doses, a digital kitchen scale is always more reliable than a spoon.
| Measure | Whole Seeds | Ground Powder |
|---|---|---|
| ¼ teaspoon | ~1.25g | ~0.9–1g |
| ½ teaspoon | ~2.5g | ~1.75–2g |
| 1 teaspoon | ~5g | ~3.5–4g |
| 2 teaspoons | ~10g | ~7–8g |
| 1 tablespoon (3 tsp) | ~15g | ~10–12g |
| 2 tablespoons | ~30g | ~20–24g |
| ¼ cup | ~60g | ~40–42g |
| ½ cup | ~120g | ~80–85g |
| 1 cup | ~240g | ~160–170g |
Why the difference? Whole seeds have air gaps between them when spooned, while ground powder settles and compacts more tightly — so a level teaspoon of powder actually weighs less than a level teaspoon of intact seeds, even though it’s the same seed, just milled.

🔍 Why Different Sources Give Different Gram Weights
If you’ve compared a few conversion pages, you’ve probably noticed the numbers don’t all match — and that’s worth explaining rather than hiding. Two different conventions are floating around online, and they answer two different questions:
| Standard | 1 tsp Whole Seeds | 1 tbsp Whole Seeds | 1 Cup Whole Seeds | Where it comes from |
|---|---|---|---|---|
| Common kitchen rounding | ~5g | ~15g | ~240g | The “1 tsp ≈ 5g” rule of thumb used across most cooking and supplement-dosage content, for easy mental math |
| USDA-sourced lab density | ~3.7g | ~11.1g | ~188g | USDA FoodData Central’s measured density for fenugreek seed, used by nutrition databases and food-science converters |
Both numbers are “correct” in the sense that neither is a typo — they’re measuring slightly different things. The 5g rounding is a practical convention (easy to divide, close enough for cooking, and it’s what most dosage guides — including our own — use for simple math like “2 tsp ≈ 10g”). The 3.7g figure comes from an actual weighed sample logged in USDA’s food database, and tends to be what you’ll get if you tare a scale and spoon in seeds without deliberately heaping them.
Does this matter for dosing? If a guide tells you “10g of fenugreek seeds” and you scoop 2 rounded teaspoons assuming 5g each, you might actually be getting closer to 7.5–8g by the USDA figure — a meaningful gap for a therapeutic dose. When precision matters (medical or supplement dosing rather than a recipe), weigh on a digital scale instead of counting spoons either way.
🌱 Fenugreek Seed Nutrition Per Teaspoon
Since you’re already measuring by the teaspoon, here’s what that teaspoon actually contains (USDA data, 1 tsp ≈ 3.7g whole seeds):
| Nutrient | Per 1 tsp (~3.7g) | Per 1 tbsp (~11g) |
|---|---|---|
| Calories | 12 | 36 |
| Protein | 0.85g | 2.55g |
| Carbohydrate | 2.16g | 6.5g |
| Dietary fibre | 0.9g | 2.7g |
| Fat | 0.24g | 0.7g |
| Iron | 1.24mg (≈7% DV) | 3.7mg (≈21% DV) |
| Calcium | 7mg | 21mg |
| Potassium | 28mg | 84mg |
The iron content is why fenugreek water is often recommended for hair and general wellness — see our fenugreek for hair guide for how this ties into hair-health dosing specifically.
📏 Measuring Accurately at Home
For everyday cooking, a level teaspoon is close enough. But measuring spoons vary by up to 20% depending on how tightly you pack them, whether the seed is heaped or level, and even the exact spoon set you own. If you’re using these conversions for a specific therapeutic dose from our fenugreek dosage guide rather than a recipe, weigh on a digital kitchen scale that reads in 0.1g increments — it removes the guesswork entirely and only costs a few dollars.
Fastest accurate method: Tare an empty bowl on your scale to 0.0g, then add seeds or powder until the scale reads your target weight. This takes under 30 seconds and is far more consistent than counting spoons.
One more mix-up worth flagging: kasuri methi (dried fenugreek leaves) is a completely different ingredient by weight and use from fenugreek seeds — a tablespoon of dried leaves is light and fluffy compared to the same volume of dense seeds, and the two are never interchangeable gram-for-gram in a recipe or a dose. If you’re not sure which one a recipe or supplement label means, see our fenugreek leaves vs seeds guide before converting.
Teaspoon to Grams — FAQs
A level teaspoon of whole fenugreek seeds weighs approximately 5 grams, and contains roughly 180–220 individual seeds — the exact count depends on seed size, which varies slightly by crop and origin. A heaped teaspoon can weigh closer to 6–6.5g. Weight is a more reliable way to measure than counting seeds, especially for consistent dosing.
1 level teaspoon of whole fenugreek seeds equals approximately 5 grams. 1 level teaspoon of ground fenugreek powder equals approximately 3.5–4 grams, because ground powder packs more densely into the spoon’s volume than whole seeds do, despite being the same underlying material.
1 level tablespoon of whole fenugreek seeds weighs approximately 15 grams (equal to 3 teaspoons). 1 tablespoon of ground fenugreek powder weighs approximately 10–12 grams. This scales linearly, so 2 tablespoons of seeds is about 30g, and so on.
1 cup of whole fenugreek seeds weighs approximately 240 grams. 1 cup of ground fenugreek powder weighs approximately 160–170 grams. This is mostly relevant for bulk cooking or making a large batch of fenugreek water — most individual servings and supplement doses are measured in teaspoons, not cups.
No. Ground fenugreek powder is denser per teaspoon of volume than whole seeds — a level teaspoon of powder is approximately 3.5–4g versus approximately 5g for a level teaspoon of whole seeds. Grinding eliminates the air gaps that exist between whole seeds, so more mass fits in the same spoon volume even though it weighs less per spoon overall due to how it settles. If a recipe or dose is given in grams rather than teaspoons, always use the gram figure directly rather than converting through teaspoons twice.
Standard measuring spoons can vary by up to 20% in actual volume depending on the manufacturer, and how “level” a level teaspoon is depends on technique — some people round the seeds slightly above the rim without realising it. Seed size also varies naturally by harvest and origin. For everyday cooking this variance doesn’t matter. For a precise therapeutic dose, use a digital kitchen scale rather than a spoon — see our fenugreek dosage guide for exact gram targets by health goal.
Two different conventions are in circulation. Most cooking and dosage content rounds to a simple “1 tsp ≈ 5g” for easy mental math. Nutrition databases and food-science converters instead use USDA FoodData Central’s measured density, which comes out closer to 3.7g per level teaspoon for whole seeds. Neither is wrong — one is a practical rounding, the other is a lab-weighed figure — but if you’re following a precise dose rather than eyeballing a recipe, the USDA figure (or a kitchen scale) is more reliable. Use the “Reference Standard” toggle in the calculator above to switch between the two.
1 teaspoon (about 3.7g) of whole fenugreek seeds contains approximately 12 calories, with 0.85g protein, 2.16g carbohydrate (including 0.9g fibre), and 0.24g fat, per USDA data. It’s also a modest source of iron — about 7% of daily value per teaspoon. See the full nutrition table above for tablespoon amounts too.
