120 Grams of Flaxseeds in Cups
120 grams of flaxseeds doesn't land on a clean fraction, so the result below is calculated exactly rather than rounded to a common measure. Based on a density of 150g per cup, it equals 0.80 cups.

120 grams of flaxseeds = 0.80 cups (¾ cup / 12.8 tbsp / 38.4 tsp)
Flaxseeds has a density of approximately 150g per cup. Whole flaxseed. Ground flaxseed is closer to 120g per cup. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.
| Grams | Cups | Fraction | Tablespoons | Teaspoons |
|---|---|---|---|---|
| 100g | 0.67 | ⅔ | 10.7 | 32.0 |
| 110g | 0.73 | ¾ | 11.7 | 35.2 |
| 120g | 0.80 | ¾ | 12.8 | 38.4 |
| 125g | 0.83 | ⅞ | 13.3 | 40.0 |
| 130g | 0.87 | ⅞ | 13.9 | 41.6 |
How 120g Converts, Step by Step
120g divided by 150g (the weight of one cup of flaxseeds) equals 0.80 cups. Multiplying that by 16 gives 12.8 tablespoons, and by 48 gives 38.4 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Flaxseeds is lighter than water, which weighs about 236g per cup. That's why 120g of flaxseeds takes up more volume (189ml) than the same weight of water would (120ml). For a side-by-side look at how other ingredients compare, see the 120 grams to cups page.
If You're Using a Metric or Imperial Cup
The 0.80 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 120g, that's ¾ metric cups or ⅔ imperial cups of flaxseeds, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling This 120g Amount
Doubling a recipe that calls for 120g of flaxseeds means weighing 240g, or measuring 1.60 cups if you're working by volume instead of weight. Halving it means 60g, or 0.40 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.
Flaxseeds Next to Other Nuts & Seeds
Within nuts & seeds, density still varies by ingredient. At 120g, almonds (143g per cup) measures ⅞ cup, while chia seeds (160g per cup) measures ¾ cup, compared to ¾ cup for flaxseeds. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where This Amount Shows Up in Recipes
- A flax egg substitute uses about 7g of ground flaxseed mixed with water.
- Baked goods often call for 30g to 50g mixed into the dry ingredients.
- Smoothies usually need just 10g to 15g.
Measuring This Precisely
Nuts & Seeds
Spoon in loosely and level off. Avoid shaking the cup, which settles the seeds and packs in more than the recipe expects.
For exact results
Whole nuts and seeds measure differently than chopped or ground versions of the same ingredient, since chopping reduces air pockets between pieces and increases the weight per cup.

Frequently Asked Questions
What is 120 grams of flaxseeds in cups exactly?+
120 grams of flaxseeds equals 0.80 cups, based on a density of 150g per cup.
Why doesn't 120g of flaxseeds match a simple fraction?+
120g isn't a multiple of flaxseeds's per-cup weight, so the cup value lands between common fractions. The closest practical measure is ¾ cup.
What's the most reliable way to measure 120g of flaxseeds?+
A kitchen scale set to grams gives an exact 120g reading. Cups only approximate this amount, since ¾ cup rounds to the nearest practical fraction.
Is 120g likely a typo for a rounder amount?+
Possibly, if a recipe seems to expect a cleaner number. Check the nearby amounts table below for the closest common gram values for flaxseeds.
