There are about 4 cups in a pound of Walnuts. Walnuts weighs 113 g per cup (spooned and levelled), so a pound — 453.59 g — divides to 4.01 cups. Chopped walnut pieces with a rich, slightly bitter flavour. Brownies, salads, pesto and banana bread. Every figure on this page is approximate, because a cup measures volume and the weight depends on how the ingredient settles and how it was measured; when the amount matters — a cake, a sauce that must set, a dough that must rise — weigh the Walnuts on a kitchen scale instead of trusting the cup. This page gives you the full table for a pound and beyond, worked examples from real recipes, the method behind the figure, and the mistakes that catch people out.
How many cups in a pound of Walnuts?
A pound of Walnuts is about 4 cups (4.01 cups, to be exact). The table below covers a quarter of a pound up to ten pounds, so you can read off whatever your recipe or your bulk buy calls for without doing the division yourself. If your recipe lists Walnuts in grams, the same table works in reverse: find the grams and read across to the cups.
| Amount | Cups | Grams | Tablespoons | Millilitres |
|---|---|---|---|---|
| 0.25 lb | 1.00 | 113 | 16 | 237 |
| 0.5 lb | 2.01 | 227 | 32 | 475 |
| 0.75 lb | 3.01 | 340 | 48 | 712 |
| 1 lb | 4.01 | 454 | 64 | 950 |
| 2 lb | 8.03 | 907 | 128 | 1899 |
| 5 lb | 20.07 | 2268 | 321 | 4749 |
| 10 lb | 40.14 | 4536 | 642 | 9497 |
The tablespoons column is the useful one for small amounts: a pound of Walnuts is about 64 tablespoons, and a single tablespoon weighs about 7.1 g. Use the pounds to grams converter if your recipe lists a different weight, and the cups to grams converter if you need the figure for a single cup of walnuts.
How the maths works
The conversion is a single division: one pound is 453.59 g, and one cup of Walnuts weighs 113 g, so 453.59 ÷ 113 = 4.01 cups. Going the other way, one cup of Walnuts weighs 113 g, which is 0.25 lb, and one tablespoon weighs about 7.1 g while one teaspoon weighs about 2.35 g. To get any number of cups, weigh that many times 113 g: two cups is 226 g, three cups is 339 g, and half a cup is 56 g. In volume terms, a pound of Walnuts is about 950 ml, since one US cup is 236.6 ml. Remember that the cup is a volume and the pound is a weight, so this maths only works because we know the density of Walnuts; the same pound of a different ingredient would be a different number of cups entirely.
Worked examples
The examples below use real recipes, with the cups and the grams side by side so you can follow the maths in context. Each one also notes where the cup is good enough and where the scale earns its keep.
A tray of brownies
A tray of brownies needs 1 cup of Walnuts — about 113 g — one cup roughly chopped and folded into the batter. Toast the walnuts for ten minutes before folding them in; raw walnuts taste soft and slightly bitter against rich chocolate.
Banana bread for the weekend
Banana bread for the weekend needs 1 cup of Walnuts — about 113 g — chopped into a loaf with very ripe bananas. One cup is about 113 g, and a pound of walnuts is about four cups, so one bag covers four loaves of banana bread.
A salad for eight
A salad for eight needs 1/2 cup of Walnuts — about 56 g — scattered over greens with blue cheese and pears. Half a cup is about 57 g; candied walnuts work here too, but keep them separate until serving or they soften in the dressing.
How the figure was measured
The weight figure on this page comes from King Arthur Baking: Walnuts weighs 113 g per cup, measured spooned and levelled, and that figure carries high confidence in CookScale's 120-ingredient table. All weights are per US cup (236.6 ml), and every cup-based result on this page is approximate, because a cup measures volume while the weight depends on how the ingredient settles, how fresh it is, and how it was measured. When the amount matters — a cake, a sauce that must set, a dough that must rise — weigh the Walnuts on a kitchen scale instead of trusting the cup. Read more about this ingredient on the Walnuts hub, which covers its weight, its measures, its storage and its substitutes in one place.
How to measure it
Spoon Walnuts into a dry cup measure and level it off — never pack them down, and never scoop the cup through the bag. Whole nuts, halves and chopped pieces all measure differently in the same cup, because the pieces settle differently and the air gaps change. If a recipe says '1 cup chopped', chop first and then measure; if it says '1 cup, chopped', measure first and then chop. When it matters, weigh: 113 g of Walnuts is 113 g however you chop them.
Practical guidance
Nuts go rancid faster than almost anything else in the pantry because their oils are exposed to air. Refrigerate or freeze; walnut oils turn rancid quickly. Freeze walnuts if you buy in bulk; their oils turn rancid faster than any other nut in this list. Buy smaller bags more often rather than one huge bag that sits open, and taste one before baking with an old bag: fresh nuts taste sweet and clean, stale ones taste like old oil.
Why recipes ask for a pound of Walnuts
Walnuts are sold by weight in bags and bulk bins, while recipes call for cups, so the pound conversion is the bridge between the bag label and the recipe. A pound is about four cups, and the usual 8 oz bag holds about two cups, which covers a tray of brownies or two loaves of banana bread.
Buying and storing a pound of Walnuts
A pound of nuts is the standard bag size, and the price per pound drops sharply in bulk bins and warehouse packs. Only buy the big bag if you have freezer space — nuts keep for a year in the freezer and for months in the fridge, but only weeks in a warm cupboard.
Frequently asked questions
How many tablespoons are in a pound of Walnuts?
About 64 tablespoons. A pound of Walnuts is about 4.01 cups, and there are 16 tablespoons in a cup, so 4.01 × 16 is about 64. A single tablespoon weighs about 7.1 g.
Do whole and chopped Walnuts measure the same?
No. Chopped Walnuts pack tighter, so a cup of chopped pieces weighs more than a cup of whole ones. The 113 g per cup figure is for Walnuts spooned and levelled as sold — weigh them if the recipe is a cake where the amount matters, and chop after measuring if the recipe says '1 cup, chopped'.
How many cups are in an 8 oz bag of Walnuts?
About 2.01 cups. An 8 oz bag weighs 227 g, and at 113 g per cup that divides to 2.01 cups. A full pound bag is double that, about 4.01 cups.
How long does a pound of Walnuts keep?
Refrigerate or freeze; walnut oils turn rancid quickly. In practice, a pound lasts a few weeks in a cupboard, months in the fridge and up to a year in the freezer. Taste one before baking with an old bag — fresh nuts taste sweet and clean, stale ones taste like old oil.
Are walnut halves the same weight per cup as chopped walnuts?
No — chopped walnuts pack tighter, so a cup of chopped walnuts weighs more than a cup of halves. The 113 g per cup figure is for chopped walnuts spooned and levelled; weigh halves on a scale if the recipe is a cake where the amount matters.
