Macadamia nuts are one of the richest sources of calories among tree nuts: a single tablespoon of whole macadamia nuts contains roughly 59–60 calories, and a tablespoon of chopped nuts can push that closer to 67–70 calories. Because they are so energy-dense, serving size matters a lot when you are tracking calories, meal-prepping keto snacks, or building a balanced diet. This calculator converts your portion—in tablespoons or grams—into total calories, serving weight, and a full macronutrient breakdown (fat, protein, and carbs). It also lets you adjust the calorie-per-100g value if you are working from a specific brand or package label. Perfect for fitness enthusiasts, keto dieters, and anyone who wants accurate numbers without pulling out a food scale.
Just enter your amount, choose tablespoons or grams, and hit Calculate.
🥜 Macadamia Calories Per Tablespoon Calculator
Quickly estimate the calories and macros in any serving of macadamia nuts.
Quick Start
Use the calculator to find calories in any macadamia portion. Enter the number of tablespoons or grams, pick the nut form (whole, chopped, or ground), and adjust the calorie-per-100g value if your package label differs from the default. Press Calculate to see total calories, serving weight, calories per tablespoon, and a fat/protein/carb breakdown. The reset button clears the form and restores default values. For meal preppers, fitness tracking apps, or keto bakers, this tool saves time by doing the math instantly. You can also use it to scale recipes: enter double the tablespoons to see a larger batch's totals.
Why Macadamia Nuts Are So Calorie-Dense
Macadamias contain roughly 75.8 grams of fat per 100 grams, which is higher than most other nuts. Fat supplies about 9 calories per gram, while protein and carbohydrates supply about 4 calories per gram. That means over 85% of the energy in macadamias comes from fat. A 100-gram portion provides about 718 calories, so even a modest handful can add 150–200 calories to a meal plan. Most of the fat is monounsaturated, the same heart-healthy type found in olive oil. This makes macadamias a nutrient-dense choice for keto or low-carb diets, but portion control is key for general calorie tracking. Their rich, buttery texture also makes them easy to overeat, which is why accurate serving measurements are so useful.
Tablespoons vs. Grams: Which Measurement Is Better?
A tablespoon is a volume measure, not a weight measure. Depending on how the nuts are cut and how tightly they are packed, one tablespoon can weigh between 8 and 11 grams. This is why nutrition labels usually list values per 100g or by weight. Macadamia nuts are one of the least standardized foods to measure by volume because their shape creates irregular air pockets. The table below shows typical weights used in this calculator.
| Nut form | Approx. weight per tbsp | Calories per tbsp |
|---|---|---|
| Whole / halves | 8.2 g | ~59 kcal |
| Chopped | 9.4 g | ~67 kcal |
| Ground / meal | 11.0 g | ~79 kcal |
If a recipe specifies 'one tablespoon of macadamia nuts,' it usually means chopped nuts unless it says 'whole.' Weighing is always the most reliable method because it removes the guesswork from spoon packing.
Estimated Nutrition Reference
The following values are based on raw macadamia nuts from USDA nutrient data. Your brand may vary slightly, especially if the nuts are oil-roasted or salted.
| Nutrient | Per 100 g | Per 1 tbsp whole (8.2 g) |
|---|---|---|
| Calories | 718 kcal | 59 kcal |
| Fat | 75.8 g | 6.2 g |
| Carbohydrate | 13.8 g | 1.1 g |
| Protein | 7.9 g | 0.6 g |
| Fiber | 8.6 g | 0.7 g |
| Sugar | 4.6 g | 0.4 g |

Common Questions
How many macadamia nuts are in one tablespoon? About 6–8 whole kernels for medium-sized nuts, depending on variety and size. Since individual nuts vary, weighing is more accurate than counting.
Can I use this calculator for roasted or salted macadamias? Yes. Dry-roasted nuts typically have similar calories, but oil-roasted varieties can be slightly higher. Update the calorie-per-100g field using the number on your package if it differs from 718.
Why does my food scale show a different number? The densities in this calculator are averages. Differences in nut size, chop, and packing can change the weight by 10% or more.
Are macadamias good for weight loss? They are filling and rich in healthy fat, but their high energy density means portions should be measured. A small handful is a reasonable serving.

Tips for Accurate Tracking
1. Weigh nuts in grams whenever possible; it removes the variability of spoon packing. 2. Use dry measuring spoons, not eating spoons. 3. For recipes, add nuts by weight rather than by volume. 4. If your package label lists per 100g, set the custom calorie field to match. 5. Remember that macadamias are often sold roasted; check whether the label says 'dry roasted' or 'oil roasted' because the fat content can differ slightly. 6. For consistent food logs, enter the same nut form each time so your entries stay comparable.
