Calories in an Ounce of Almonds, Cashews, Walnuts

By NYUS Inc. · Published 28 October 2026

Almonds, cashews, walnuts, pistachios and peanuts each have an ounce, a cup and often a single-nut weight printed on their SR Legacy record page. This guide gives fifteen nut and seed records from the SR Legacy table of USDA FoodData Central (almonds, cashews, walnuts, pistachios, peanuts, hazelnuts, pecans, Brazil nuts, macadamia nuts, pine nuts and pumpkin seed kernels, some raw and some dry roasted), with the portion weights printed on their record pages. IFCT 2017, the Indian Food Composition Tables from ICMR-NIN, prints per 100 g only and has no ounce or cup weights, so this page uses SR Legacy only. Calories per nut from IFCT rows and our own weights are in our calories per piece guide.

The short answer

By the SR Legacy records, 1 oz (28.35 g) of almonds is 164.1 kcal, 1 oz of raw cashew nuts 156.8 kcal and 1 oz of walnuts 185.4 kcal. Our reading: an ounce holds very different numbers of nuts, 23 whole kernels for almonds but 167 kernels for pine nuts, and the kcal per ounce differ much less than the counts: 156.8 kcal for the lowest ounce here (raw cashew nuts) and 203.6 kcal for the highest (macadamia nuts).

SR Legacy: per 100 g

Every figure below is exactly as the record page shows it. The record names are the dataset's own.

SR Legacy: per printed portion

Each figure is our arithmetic on exact weights: kcal per 100 g times the grams, divided by 100, with the exact product in the sums line and the result shown to 0.1 with half rounding up. Every weight below is printed on the SR Legacy record page; none is ours. The ounce, single-nut, tablespoon and whole-kernel cup portions are listed; the records also print other cups (ground, slivered, sliced, chopped, pieces) and in-shell portions, which are not used here, and each record prints 100 g.

The sums: 170567 579 × 28.35 / 100 = 164.1465, so 164.1 kcal; 170567 579 × 1.2 / 100 = 6.948, so 6.9 kcal; 170567 579 × 143 / 100 = 827.97, so 828.0 kcal; 170158 598 × 28.35 / 100 = 169.533, so 169.5 kcal; 170158 598 × 138 / 100 = 825.24, so 825.2 kcal; 170162 553 × 28.35 / 100 = 156.7755, so 156.8 kcal; 170571 574 × 28.35 / 100 = 162.729, so 162.7 kcal; 170571 574 × 8.6 / 100 = 49.364, so 49.4 kcal; 170571 574 × 137 / 100 = 786.38, so 786.4 kcal; 170187 654 × 28.35 / 100 = 185.409, so 185.4 kcal; 170187 654 × 100 / 100 = 654, so 654.0 kcal; 170184 560 × 28.35 / 100 = 158.76, so 158.8 kcal; 170184 560 × 0.7 / 100 = 3.92, so 3.9 kcal; 170184 560 × 123 / 100 = 688.8, so 688.8 kcal; 170185 572 × 28.35 / 100 = 162.162, so 162.2 kcal; 170185 572 × 0.7 / 100 = 4.004, so 4.0 kcal; 170185 572 × 123 / 100 = 703.56, so 703.6 kcal; 172430 567 × 28.35 / 100 = 160.7445, so 160.7 kcal; 172430 567 × 146 / 100 = 827.82, so 827.8 kcal; 173806 587 × 28.35 / 100 = 166.4145, so 166.4 kcal; 173806 587 × 1 / 100 = 5.87, so 5.9 kcal; 173806 587 × 146 / 100 = 857.02, so 857.0 kcal; 170581 628 × 28.35 / 100 = 178.038, so 178.0 kcal; 170581 628 × 14 / 100 = 87.92, so 87.9 kcal; 170581 628 × 135 / 100 = 847.8, so 847.8 kcal; 170182 691 × 28.35 / 100 = 195.8985, so 195.9 kcal; 170182 691 × 99 / 100 = 684.09, so 684.1 kcal; 170569 659 × 28.35 / 100 = 186.8265, so 186.8 kcal; 170569 659 × 5 / 100 = 32.95, so 33.0 kcal; 170569 659 × 133 / 100 = 876.47, so 876.5 kcal; 170178 718 × 28.35 / 100 = 203.553, so 203.6 kcal; 170178 718 × 134 / 100 = 962.12, so 962.1 kcal; 170591 673 × 28.35 / 100 = 190.7955, so 190.8 kcal; 170591 673 × 1.7 / 100 = 11.441, so 11.4 kcal; 170591 673 × 135 / 100 = 908.55, so 908.6 kcal; 170556 559 × 28.35 / 100 = 158.4765, so 158.5 kcal; 170556 559 × 129 / 100 = 721.11, so 721.1 kcal.

Why these are reference rows, not your plate

• Names are the records'. We do not say that nuts from a shop, a dry-fruit box or a mithai counter match any record, and the record names are used exactly as printed. No record here is soaked, ghee-roasted, masala, salted or sweetened.
• A handful is not a record portion. No record prints a handful. The ounce is 28.35 g; we do not say how many grams your handful is.
• Every portion here is printed. No ounce, cup, tablespoon or single-nut weight on this page is ours: each is printed on its record page, and the only weight that is ours is the labelled 10 g example in the logging section. The weights in our calories per piece guide are our own and are not used here.
• The records' own notes. The record pages mark the kcal energy of all fifteen records "Calculated". Protein and fat are mostly "Analytical"; 170571 protein and fat, 173806 fat and 170162 fat carry no note or an imputing note. They are USDA values, not our measurements.
• For a packaged product, the pack wins. This page uses no pack labels.

How to log it so the numbers hold

• Log by weight. 10 g of raw almonds (our example weight, not a dataset value) on SR Legacy 170567 is 579 × 10 / 100 = 57.9, so 57.9 kcal.
• Pick raw or roasted as the pack says. Raw and dry roasted are different rows: the same weight gives different calories.
• Oil and salt are separate. Ghee or oil used to roast nuts is in our spoon guide, and nut butters in our spreads guide.
• Do not mix datasets inside one day. If you log nuts from SR Legacy, keep to that record for the same snack.

Where NYUS fits (our app)

We make NYUS, so read this as ours. NYUS is an AI fitness and nutrition coach in early access on Android, with no ads and no data selling. You log foods yourself by searching 8,900+ Indian and global foods or by barcode, and a weekly check-in adjusts your calories, macros and step goal once enough is logged. Barcode coverage of Indian packaged foods is not complete, so search by name when a scan finds nothing.

What this page leaves out

• A calorie or fat target, and any claim about what nuts do to your weight or health: we have not looked up one for any person, so we give none. If you have a medical condition, ask your doctor or dietitian.
• Soaked, ghee-roasted, masala and sweetened nuts, nut mixes and chikki: no record used here. Peanut chikki and banana chips are in our banana chips and chikki guide.
• Other nut and seed records in the SR Legacy list are left out, for example blanched, oil-roasted, salted and honey-roasted almonds, mixed nuts, chestnuts and the other cup cuts.
• Dates, raisins and other dried fruit are in our dried fruit guide, and flax, sesame, sunflower and poppy seeds in our seeds guide.
• Nutrients beyond energy, protein, fat and carbohydrate: not covered here.
