Pecans are a rich, buttery nut with surprisingly little sugar relative to their weight. In a typical 100 g serving of raw pecan halves, total sugars come to about 3.97 g — roughly a third of the sugar found in the same weight of banana and far less than most snack mixes. That makes pecans a smart choice for low-sugar and low-carb eating plans.
This calculator converts your pecan portion into grams of sugar using that per-100 g baseline, so you can log snacks, plan desserts, or compare products without hunting through nutrition labels. Whether you track macros, follow a low-sugar diet, or simply want to know how much sweetener is being added to glazed or candied pecans, this tool gives you a quick estimate. Adjust the sugar value for dry-roasted or custom products, use grams, ounces, or cups, and get an instant per-serving calculation with the math shown step by step.
🥜 Pecan Sugar Per 100g Calculator
Estimate the total sugar in any pecan portion — in grams, ounces, or cups.
How the Calculation Works
This tool uses the standard nutrition-label method: compare your portion to a 100 g reference. Because raw pecans contain about 3.97 g of total sugar per 100 g, the sugar content scales linearly with mass. Any portion unit — grams, ounces, or cups of halves — is first converted to grams, then multiplied by the sugar density and divided by 100. The result is the total sugar in your portion, not including sugar alcohols or fiber.
Worked Examples
Example 1 — Small snack: A 30 g handful of raw pecans → 30 × 3.97 ÷ 100 = 1.19 g of sugar. That is less than a quarter of a typical sugar packet, which holds about 5 g.
Example 2 — Standard serving: A 1 oz portion (28.35 g) of dry-roasted pecans at 4.17 g/100 g → 28.35 × 4.17 ÷ 100 = 1.18 g of sugar — nearly identical to the raw version despite the slightly higher density.
Example 3 — Half cup: Half a cup of pecan halves (about 50 g) → 50 × 3.97 ÷ 100 = 1.99 g of sugar. Two half-cup servings still land under 4 g.
Example 4 — Recipe total: Baking a pecan pie with 200 g of pecans → 200 × 3.97 ÷ 100 = 7.94 g of sugar from the nuts alone. The corn syrup, brown sugar, and other ingredients contribute far more, which is why the finished pie contains several times this amount.
Reference Sugar Values for Pecans
| Product | Total sugar per 100 g | Notes |
|---|---|---|
| Raw pecan halves | 3.97 g | USDA FoodData Central baseline |
| Dry roasted pecans | 4.17 g | Moisture loss raises the density slightly |
| Oil roasted pecans | 4.06 g | Fat is absorbed, sugar stays similar |
| Honey-roasted / glazed pecans | 20–35 g | Added sugar dominates; check the label |
| Candied / praline pecans | 40–60 g | Varies widely by recipe |
Raw, dry-roasted, and oil-roasted values come from the USDA FoodData Central database (survey-average entries). Coated products are made with added sweeteners, so their numbers depend on the brand recipe — always use the package label when one is available.
Tips for Accurate Estimates
- Weigh pecans on a kitchen scale — cup volume can vary 10–15% depending on how tightly halves are packed, so weight-based estimates are more reliable than volume-based ones.
- Remember this is total sugar, not net carbs. Pecans also provide about 10 g of fiber and roughly 72 g of fat per 100 g, so their overall carbohydrate impact is low.
- For coated or flavored pecans, switch to Custom and enter the per-100 g number printed on the nutrition label; that captures any added sugar accurately.
- Roasting without sweeteners adds no sugar, but it removes moisture, which is why dry-roasted pecans show a slightly higher per-100 g figure than raw.
- When tracking macros, count the sugar from pecans as part of your daily carbohydrate allowance even though the amount is modest.
Frequently Asked Questions
Are pecans high in sugar? No. At about 4 g per 100 g, pecans are among the lowest-sugar tree nuts. Walnuts (~2.6 g) and macadamias (~4.6 g) are similar; almonds (~4.4 g), cashews (~5.9 g), and pistachios (~7.7 g) sit a bit higher. Even a generous 100 g handful of raw pecans delivers less sugar than a single medium banana (~12 g).
Can this handle a whole recipe? Yes — enter the total weight of pecans used and the sugar value from your ingredient label, and you get the aggregate sugar contributed by the pecans alone. For a recipe with several nut ingredients, run the calculation once per ingredient and add the results.
Why don't raw and dry-roasted values match? Both start with the same sugar content, but roasting drives off water. The same amount of sugar ends up in a slightly smaller mass, so the per-100 g figure rises from 3.97 g to 4.17 g.
Where is the official data? The USDA FoodData Central database (fdc.nal.usda.gov) provides full nutrient profiles for raw, dry-roasted, and oil-roasted pecans. Search for 'pecans' to compare the entries side by side.
