120 g of pistachios is 1 cup. That is the whole answer: one US cup of pistachios weighs 120 g (spooned and levelled, King Arthur Baking), so 120 g divided by 120 g per cup is exactly 1 cup. All the figures on this page are approximate — pistachios is a natural product, and how it is measured moves the weight of a cup by a few grams — so when the recipe is delicate, verify with a kitchen scale. For everyday cooking, 1 cup is the number to use.

This page is the reverse of the usual conversion: most recipes list pistachios in cups and the cook wants grams, but here the recipe, the packet or the scale gives grams and the cook has only cup measures. That happens more often than people expect — imported recipes, nutrition labels, bulk packs and meal-prep plans all speak in grams, while American cup measures are what is actually in the drawer. The conversion is one division, 120 ÷ 120 = 1, and the table below runs the same division for the amounts that come up most often.

120 grams of pistachios in cups — conversion table

Grams Cups (approx.)
10 g 0.08 (1/8 cups)
25 g 0.21 cups
50 g 0.42 cups
75 g 0.62 (5/8 cups)
100 g 0.83 cups
125 g 1.04 (1 cup)
150 g 1.25 (1 1/4 cups)
200 g 1.67 (1 2/3 cups)
250 g 2.08 (2 1/8 cups)
300 g 2.50 (2 1/2 cups)
400 g 3.33 (3 1/3 cups)
500 g 4.17 cups

Read the table from left to right: find the grams you have, and the cups column tells you how much that is, approximately. A quarter of a cup is 30 g, half a cup is 60 g, and three quarters is 90 g. For amounts between the rows, divide the grams by 120: for example, 90 g is 0.75 (3/4 cups), and 180 g is 1.50 (1 1/2 cups). The same 120 g figure works in the other direction too — multiply cups by 120 to get grams — and the second table runs that calculation for the common cup fractions.

Cups Grams (approx.)
1/4 cup 30 g
1/3 cup 40 g
1/2 cup 60 g
2/3 cup 80 g
3/4 cup 90 g
1 cup 120 g
1 1/2 cups 180 g
2 cups 240 g

Scaling a spice blend for a market stall or a big batch

A rub or curry powder made in bulk from a recipe written in grams. Take the 60 g figure first: 60 g of pistachios is 0.50 (1/2 cups), because 60 divided by 120 is 0.50. In practice that means a recipe calling for 0.50 (1/2 cups) can be weighed out as 60 g and poured or spooned straight in, with no jug to wash. The habit to build is converting once, writing the cup figure on the recipe, and then cooking from the cups — the scale only comes out for the first batch, and after that the converted recipe is a cup recipe. If the amount is awkward, round to the nearest tablespoon: one tablespoon of pistachios weighs about 7.5 g, so a couple of spoonfuls either way covers most rounding gaps without anyone noticing in the finished dish.

A bakery that buys leavener by the kilo

A professional kitchen converting a bulk bag into cup measures for a daily bake. Take the 180 g figure first: 180 g of pistachios is 1.50 (1 1/2 cups), because 180 divided by 120 is 1.50. In practice that means a recipe calling for 1.50 (1 1/2 cups) can be weighed out as 180 g and poured or spooned straight in, with no jug to wash. The habit to build is converting once, writing the cup figure on the recipe, and then cooking from the cups — the scale only comes out for the first batch, and after that the converted recipe is a cup recipe.

A preserving or pickling recipe written in grams

A spice mix where the exact balance keeps the flavour right across dozens of jars. Take the 240 g figure first: 240 g of pistachios is 2.00 (2 cups), because 240 divided by 120 is 2.00. In practice that means a recipe calling for 2.00 (2 cups) can be weighed out as 240 g and poured or spooned straight in, with no jug to wash. The habit to build is converting once, writing the cup figure on the recipe, and then cooking from the cups — the scale only comes out for the first batch, and after that the converted recipe is a cup recipe.

Measuring pistachios the spooned and levelled way

The 120 g figure only holds when pistachios is measured the way King Arthur Baking measured it: spooned and levelled. For a dry ingredient, that means spooning it into the cup rather than scooping with the cup itself, then sweeping a knife across the top to level it. Scooping compresses the ingredient and can add a surprising amount of weight to a cup. The difference between the two approaches is not academic: a scooped cup of a powder can weigh 20 to 30 percent more than a spooned and levelled one, which is enough to change a recipe outright.

That is why the headline number on this page is labelled approximate. King Arthur Baking publishes the figure as a standard, and it is the best single number available, but your pistachios, your cup and your technique will all nudge it a gram or two in either direction. When the dish is forgiving — a soup, a salad, a roast — that nudge does not matter. When it is a cake, a custard or a batch of dough, weigh the pistachios on a kitchen scale and let the grams decide. The cup figure is a convenience for the everyday cook, not a laboratory standard, and treating it that way keeps both the recipe and the cook honest.

What pistachios is, and where it is used

Shelled pistachio kernels, green and mildly sweet. Baklava, salads, pesto and ice cream. That versatility is exactly why the conversion keeps coming up: pistachios appears in recipes written on both sides of the Atlantic, in both grams and cups, and a cook who can move between the two never has to stop and search mid-recipe. The storage note is worth knowing too: Airtight container in a cool place; refrigerate for longer.

Frequently asked questions

How many cups is 120 g of pistachios?

About 1 cup — 120 g divided by 120 g per cup. The figure is approximate, because fine powders compact differently depending on how they are spooned.

Would I ever really need a whole cup of pistachios?

In a home recipe, almost never — pistachios is used by the teaspoon. A full cup is a bulk-cooking quantity, for spice blends, restaurant batches or preserving, where grams are converted to cups for a large mixing bowl.

How should I measure pistachios for a normal recipe?

By weight or by spoon, never by the cup. One tablespoon of pistachios weighs about 7.5 g, which is the practical unit for everyday cooking.

Why is the spooned-and-levelled method important here?

Because scooping a powder straight from the jar compresses it and can add a quarter or more to the weight. Spoon the powder into the measure and level it with a straight edge.

Does humidity change the weight?

Yes — powders absorb moisture from the air, especially above a stove or in a steamy kitchen, and clump. Store pistachios in an airtight jar in a cool, dry place and the conversion stays stable.
