1 Cup Pistachios in Grams

1 cup of pistachios weighs 120 g (spooned and levelled, King Arthur Baking). Shelled pistachio kernels, green and mildly sweet. All the figures on this page are approximate conversions based on the King Arthur Baking value, so when a recipe really matters, verify with a kitchen scale.

Why weighing pistachios beats measuring it in cups

Pistachios are one of the few nuts where the shell question changes the number entirely. The 120 g figure here is for shelled kernels, the green nuts you buy ready to eat or bake with. A cup of pistachios in the shell weighs far less in edible nuts, because the shells take up most of the space and weigh almost nothing, so a recipe that calls for a cup of pistachios always means shelled unless it says otherwise. That distinction is why the conversion matters: baklava, pesto and ice cream all depend on the weight of the kernels, not the volume of the shells.

The second reason to weigh pistachios is price. They are among the most expensive nuts in the pantry, and a cup measured loosely can be 15 g short of a cup measured generously. Over a tray of baklava that uses three cups, the gap is 45 g, which is a real amount of an expensive ingredient either wasted or missing. A scale turns an expensive guess into an exact quantity, and it also lets you buy the right amount in the first place: a 200 g bag is not quite two cups, and knowing that before you start cooking saves a mid-recipe trip to the shop.

Pistachios cups to grams conversion table

Cups Grams Tablespoons
1/4 cup 30 g 4
1/3 cup 40 g 5.3
1/2 cup 60 g 8
2/3 cup 80 g 10.7
3/4 cup 90 g 12
1 cup 120 g 16
1 1/2 cups 180 g 24
2 cups 240 g 32
3 cups 360 g 48
4 cups 480 g 64

One tablespoon of pistachios weighs about 7.5 g, since a cup is 16 tablespoons. That is useful when a recipe calls for a spoonful or two rather than a whole cup, though for small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one.

Worked examples

Baklava filling for a standard tray

A classic baklava tray takes about 2 cups of finely chopped pistachios for the filling, which is 240 g. Chop the kernels in a food processor in short pulses so they stay in small pieces rather than turning to paste, then weigh 240 g and mix with 100 g of sugar and a teaspoon of cinnamon. If you measure by cups instead, chop first and then measure, because whole kernels and chopped kernels pack differently and a cup of whole pistachios chopped afterwards will not fill the same cup again.

Pistachio pesto for four servings

Pesto for four people uses about 1/2 cup of pistachios, which is 60 g, blended with basil, parmesan, garlic and olive oil. The nuts replace pine nuts and give a greener, slightly sweeter pesto. Weigh the 60 g before blending, because pesto is balanced by weight: too many nuts and the sauce turns thick and gritty, too few and it is oily and thin. Toast the kernels lightly first and let them cool, which deepens the flavour without adding anything to the weight.

Topping a batch of ice cream

A pistachio ice cream topping for a family tub uses about 3/4 cup of roughly chopped kernels, which is 90 g. Chop them coarsely so the pieces stay visible and crunchy against the soft ice cream, and weigh 90 g rather than guessing from the bag. Because pistachios are sold in shells as well as shelled, check the packet: if you bought them in the shell, you will need roughly twice the volume to get 90 g of kernels, and shelling them first is the only way to measure accurately.

How the weight was measured

Spooned and levelled means spooning the ingredient into the measuring cup until it is heaped, then sweeping a straight knife across the top to level it off. Never scoop the cup through the bag or jar, and never tap the cup down, because both pack the ingredient and add weight. The difference between a spooned cup and a scooped cup can be 15 to 25 percent, which is enough to change a bake from tender to tough, so the method matters as much as the number.

The source for the figure on this page is King Arthur Baking, and the confidence in the value is high. King Arthur Baking publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows that chart rather than any single cookbook. Where the chart gives a range or a note, we say so plainly instead of hiding the uncertainty. All the figures here are approximate conversions: natural ingredients vary by brand, variety, moisture and how finely they are chopped or ground, so when a recipe really matters, verify the weight with a kitchen scale.

Practical guidance

Buy pistachios shelled when you plan to bake with them, and keep them in an airtight container in a cool place, refrigerated for longer keeping. Their high oil content means they go rancid faster than most pantry staples, and a rancid pistachio will flavour a whole tray of baklava, so taste one before you use the bag. If the kernels smell sharp or paint-like, throw them out. When a recipe calls for salted pistachios, reduce the salt elsewhere in the recipe, because the salt on the nuts is part of the seasoning. For grinding, pulse in short bursts and stop while the pieces are still distinct: over-processing releases the oils and turns the nuts into butter, which weighs the same but behaves completely differently in a batter. If you do not have a scale, fill the cup by spooning kernels in and levelling with a knife, and remember the figure is approximate, so check the texture of the finished mixture rather than trusting the cup alone.

Common mistakes with nuts and seeds

The most common mistake is measuring whole nuts and chopped nuts as if they weighed the same. Chopped nuts pack tighter, so a cup of chopped pistachios weighs more than a cup of whole ones, and a recipe that calls for a cup of one and gets the other will be off by a noticeable margin. If a recipe says chopped, chop first and then measure, or better, weigh. The second mistake is using stale nuts: rancid oil in an old bag will flavour the whole bake, and no amount of sugar covers it. Taste one before you bake with it. The third is toasting by time instead of by smell: nuts go from toasted to burnt in under a minute, so stand at the oven and pull them when they smell fragrant, not when the timer says so. Finally, do not substitute one nut for another by volume alone in a recipe that depends on weight: a cup of cashews and a cup of hazelnuts differ by nearly 30 g, which changes the balance of a cake or a pesto.

Frequently asked questions

How many grams is 1 cup of pistachios?

1 cup of shelled pistachios weighs 120 g when spooned and levelled, according to King Arthur Baking. The figure is approximate, because kernel size and how tightly they settle vary, so verify with a kitchen scale when the recipe matters.

Is that shelled or in the shell?

The 120 g figure is for shelled pistachio kernels. Pistachios in the shell take up far more volume for the same weight of edible nut, so a cup in the shell gives you much less than 120 g of kernels. Always shell them first, then measure or weigh.

How many cups is 100 g of pistachios?

100 g of pistachios is about 0.83 cups, or roughly 3/4 cup plus a tablespoon. At 120 g per cup, divide the weight you have by 120 to get cups, and round to the nearest practical measure.

Can I use pistachios instead of pine nuts in pesto?

Yes, pistachios are a common substitute for pine nuts in pesto and are often cheaper. Use the same weight rather than the same volume, because the two nuts have different densities, and toast the pistachios lightly first for a deeper flavour.

Do chopped pistachios weigh the same as whole ones per cup?

No. Chopped pistachios pack tighter, so a cup of chopped kernels weighs more than a cup of whole ones. Chop first, then measure or weigh, and prefer weighing whenever a recipe depends on the amount of nuts.
