Understanding the Weight: How much weight is 20 cashews?
The Average Weight of 20 Cashews
Based on a standard one-ounce serving size, which is approximately 28.35 grams, 20 cashews typically weigh in the range of 28 to 30 grams. The U.S. Department of Agriculture (USDA) cites a 1-ounce (28g) serving as about 18 whole cashews, confirming that 20 nuts is a very close estimate to a standard portion. It is important to remember that this is an average, and the exact weight can fluctuate based on several factors, including the cashew's individual size and grade.
Factors Influencing Cashew Weight
Not all cashews are created equal. The weight of an individual cashew nut can differ significantly based on its grade. Cashew grades, often represented by a number like 180, 240, or 320, refer to the number of kernels per pound. Therefore, 'King size' 180 grade cashews will be heavier than the more common 320 grade. A user on Quora noted that 10 larger 240-grade cashews weighed 21 grams, making the average 2.1 grams per nut. In contrast, a study found each cashew in a 100-gram sample weighed approximately 1.4 grams.
Raw vs. Roasted: Does it Affect Weight?
The preparation method can also slightly influence the final weight. Raw cashews may contain more moisture. Dry-roasting them removes some of this water content, making them slightly lighter. However, oil-roasting can add a small amount of weight from the absorbed oil. For the purpose of portion control, these minor fluctuations are negligible, and focusing on the count or total grams is most effective.

| Calories | ~160-180 | ~164 | ~185 |
| Protein | ~5g | ~6g | ~4g |
| Total Fat | ~13-14g | ~14g | ~18.5g |
| Fiber | ~1g | ~3.5g | ~2g |
| Copper | High | Low | Medium |
| Magnesium | High | High | Medium |
Practical Tips for Mindful Cashew Snacking
Because of their satisfying texture and rich flavor, it's easy to overconsume cashews. Here are some simple strategies for portion control:
- Measure First: Use a small container or a food scale to portion out a single serving (18-20 nuts or about 28 grams) beforehand. This prevents mindless eating directly from a large bag.
- Pair with Other Foods: Incorporating cashews into a meal or alongside fruits and vegetables can make you feel fuller and more satisfied.
- Choose Wisely: Opt for unsalted, raw, or dry-roasted versions to avoid excess sodium and oil.
- Spread Them Out: If you enjoy cashews daily, consider splitting your serving throughout the day instead of eating them all at once.
Conclusion: Enjoying Cashews in Moderation
So, how much weight is 20 cashews? On average, you can expect 20 cashews to weigh between 28 and 30 grams, consistent with a healthy, standard portion size. This portion delivers a rich array of nutrients, including healthy fats, protein, and minerals like magnesium and copper, all for a reasonable calorie count. By being mindful of your portion size and employing simple strategies like pre-measuring, you can easily enjoy the numerous health benefits cashews have to offer without overdoing it.
