280 grams of walnuts = 2.39 cups (2⅜ cups / 38.3 tbsp / 114.9 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.

| 270g | 2.31 | 2⅓ | 36.9 | 110.8 |
| 275g | 2.35 | 2⅓ | 37.6 | 112.8 |
| 280g | 2.39 | 2⅜ | 38.3 | 114.9 |

How 280g Converts, Step by Step
280g divided by 117g (the weight of one cup of walnuts) equals 2.39 cups. Multiplying that by 16 gives 38.3 tablespoons, and by 48 gives 114.9 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 280g of walnuts takes up more volume (566ml) than the same weight of water would (281ml). For a side-by-side look at how other ingredients compare, see the 280 grams to cups page.
If You're Using a Metric or Imperial Cup
The 2.39 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 280g, that's 2¼ metric cups or 2 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 This 280g Amount
Doubling a recipe that calls for 280g of walnuts means weighing 560g, or measuring 4.79 cups if you're working by volume instead of weight. Halving it means 140g, or 1.20 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 Next to Other Nuts & Seeds
Within nuts & seeds, density still varies by ingredient. At 280g, almonds (143g per cup) measures 1⅞ cups, while flaxseeds (150g per cup) measures 1⅞ cups, compared to 2⅜ cups 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.
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 280 grams of walnuts in cups exactly?+
280 grams of walnuts equals 2.39 cups, based on a density of 117g per cup.
Why doesn't 280g of walnuts match a simple fraction?+
280g isn't a multiple of walnuts's per-cup weight, so the cup value lands between common fractions. The closest practical measure is 2⅜ cups.
What's the most reliable way to measure 280g of walnuts?+
A kitchen scale set to grams gives an exact 280g reading. Cups only approximate this amount, since 2⅜ cups rounds to the nearest practical fraction.
Is 280g 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 walnuts.
