150 grams of walnuts = 1.28 cups (1¼ cup / 20.5 tbsp / 61.5 tsp)
Walnuts has a density of approximately 117g per cup. Chopped. Finely ground walnuts pack denser, closer to 80g 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 |
|---|---|---|---|---|
| 130g | 1.11 | 1⅛ | 17.8 | 53.3 |
| 140g | 1.20 | 1¼ | 19.1 | 57.4 |
| 150g | 1.28 | 1¼ | 20.5 | 61.5 |
| 160g | 1.37 | 1⅜ | 21.9 | 65.6 |
| 170g | 1.45 | 1½ | 23.2 | 69.7 |
How the 150g Figure Is Calculated
150g divided by 117g (the weight of one cup of walnuts) equals 1.28 cups. Multiplying that by 16 gives 20.5 tablespoons, and by 48 gives 61.5 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Walnuts is lighter than water, which weighs about 236g per cup. That's why 150g of walnuts takes up more volume (303ml) than the same weight of water would (150ml). For a side-by-side look at how other ingredients compare, see the 150 grams to cups page.
If Your Recipe Uses Metric or Imperial Cups
The 1.28 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 150g, that's 1¼ metric cups or 1⅛ imperial cups of walnuts, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling 150g Up or Down
Doubling a recipe that calls for 150g of walnuts means weighing 300g, or measuring 2.56 cups if you're working by volume instead of weight. Halving it means 75g, or 0.64 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.
Walnuts vs. Other Nuts & Seeds
Within nuts & seeds, density still varies by ingredient. At 150g, almonds (143g per cup) measures 1⅛ cup, while flaxseeds (150g per cup) measures 1 cup, compared to 1¼ cup for walnuts. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Using Walnuts in Recipes
- Recipes typically call for this ingredient in amounts ranging from a tablespoon to a full cup, depending on the dish.
- Check your specific recipe for the exact gram amount, then use the converter above to find the matching cup measurement.
How to Measure It Accurately
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 150 grams of walnuts in cups?+
150 grams of walnuts is 1.28 cups (1¼ cup), or 20.5 tablespoons.
How do I measure 150 grams of walnuts without a scale?+
Use 1¼ cup, spooned in and leveled off with a straight edge. If you only have tablespoons, use 20.5 tablespoons instead.
Why is walnuts's gram-to-cup ratio different from other ingredients?+
Walnuts weighs 117g per cup because of its own density. Chopped. Finely ground walnuts pack denser, closer to 80g per cup.
Does a metric or imperial cup change this 150g conversion?+
Yes, slightly. 150g of walnuts is 1¼ metric cups or 1⅛ imperial cups, versus 1¼ US cups, since each cup standard holds a different volume.
