Sunflower seeds are a concentrated source of healthy fats, with roughly 51 g of fat per 100 g of shelled kernels. The Sunflower Fat Per 100g Calculator lets you quickly convert any serving size — grams, ounces, tablespoons, or cups — into fat grams, fat calories, and the percentage of total calories that come from fat. It supports raw, dry-roasted, and oil-roasted sunflower seeds, so you can compare snacks, trail mixes, and baking ingredients with confidence.
This tool is useful for anyone tracking macronutrients, following a ketogenic or low-carb eating plan, planning high-fat snacks, or simply learning how a handful of sunflower seeds fits into a daily calorie budget. Because the calculation is based on standard food-database values, you get a dependable estimate in seconds rather than guessing from a label.
The calculator also shows a step-by-step breakdown, so you can see exactly how the fat figure was derived from your serving size and the per-100g reference value.
🥜 Sunflower Fat Per 100g Calculator
Work out the total fat, fat calories, and calorie share for any sunflower seed serving.
How to Use This Tool
Start by choosing which sunflower seed product you have: raw kernels, dry-roasted kernels, or oil-roasted kernels. The fat-per-100g value is adjusted for each option. Next, enter the serving size you plan to eat and select the matching unit. Grams are the most accurate, but the tool also accepts ounces, tablespoons, and cups for common kitchen measurements. Press Calculate Fat and the result panel shows grams of fat, fat calories, estimated total calories, and the percentage of calories coming from fat. The step-by-step breakdown underneath explains each conversion so you can verify the math or use it in a nutrition assignment.
How the Fat Content Is Calculated
Shelled sunflower seed kernels are naturally high in oil. According to USDA FoodData Central, raw sunflower seed kernels contain about 51.0 g of fat per 100 g. Dry roasting removes a little moisture and concentrates the fat to roughly 51.8 g per 100 g; oil roasting adds a small amount of absorbed oil and brings the figure up to about 53.0 g per 100 g.
The reference values used by this calculator are rounded from standard nutrition data for shelled kernels:
| Seed type | Fat per 100 g | Calories per 100 g | Main fat type |
|---|---|---|---|
| Raw kernels | 51.0 g | 584 kcal | Polyunsaturated |
| Dry-roasted kernels | 51.8 g | 582 kcal | Polyunsaturated |
| Oil-roasted kernels | 53.0 g | 592 kcal | Polyunsaturated |

Worked Examples
Fat Breakdown in Sunflower Seeds
Most of the fat in sunflower seeds is unsaturated. The approximate fatty-acid profile per 100 g of raw kernels looks like this:
- Saturated fat: about 4.5 g
- Monounsaturated fat: about 18.5 g
- Polyunsaturated fat: about 23.1 g
- Omega-6 linoleic acid: about 23 g
- Omega-3 alpha-linolenic acid: about 0.07 g
Sunflower seeds also deliver vitamin E, phytosterols, and minerals such as magnesium and selenium. Even though a large share of their calories comes from fat, most of that fat is the unsaturated kind associated with heart-healthy dietary patterns when consumed in sensible portions.
Tips & Best Practices
- Weigh shelled kernels. Whole seeds still in their shells include a lot of shell weight, which would make the same weight estimate much lower in edible fat.
- If a recipe lists sunflower seeds by volume, use tablespoons or cups as a rough guide but expect some variation because seed size and packing density vary.
- For packaged sunflower seeds, the nutrition label is your most accurate source. Enter the label serving in grams and compare it with the calculator result.
- Be aware that oil-roasted, salted, or flavored products may have slightly more fat and calories than plain raw kernels.
- Use the calculator together with other nutrient tools to build a balanced meal plan; fat is only one piece of the macronutrient picture.
Frequently Asked Questions
How much fat is in 100 g of sunflower seeds? Around 51 g for raw kernels, 51.8 g for dry-roasted kernels, and 53.0 g for oil-roasted kernels. Exact values can shift slightly between crops and brands, so a packaged product label is the most precise source for that specific item.
Is sunflower seed fat healthy? Most of the fat in sunflower seeds is unsaturated, including linoleic acid, an essential omega-6 fatty acid. Sunflower seeds also contain vitamin E and plant sterols. Health authorities generally recommend replacing saturated fats with unsaturated fats from foods like sunflower seeds, nuts, and avocados, while keeping portions consistent with your calorie needs.
Should I weigh with or without the shell? With the shell removed. The calculator values are for shelled kernels. If you are eating sunflower seeds in the shell, you would need to weigh only the edible kernels to get an accurate fat estimate.
What about sunflower seed butter? Sunflower seed butter is made from ground kernels and typically has about 51–53 g of fat per 100 g. The raw kernel value in this calculator is a reasonable approximation if you do not have the exact product label handy.
Does sunflower seed contain sugar? Sunflower seeds are very low in sugar, but if you are tracking sugar as well as fat, you can check the sunflower sugar per 100g calculator for more detail. It uses the same serving-size approach for sugar values.
