The Passion Fat Per 100g Calculator converts any passion fruit portion into the standard per-100-gram fat figure used by nutrition labels and food databases. Fresh passion fruit is naturally low in fat, with most of the small amount coming from the edible seeds, but processed forms such as juice and nectar differ, and packaged labels usually list fat per serving rather than per 100 g. This tool handles both situations in one place.
Switch between Portion mode and Label mode: enter a portion weight and instantly see grams of fat, or type in the fat value and serving size printed on a pack to get the comparable per-100-g number. Results also show calories from fat and the share of your daily fat target, making the tool useful for calorie tracking, macro logging, label comparison, and low-fat meal planning.

How to Use This Tool
Choose the mode that matches the information you have on hand. In Portion mode, select the passion fruit form from the dropdown — fresh fruit with seeds, juice, or nectar — or enter a custom fat-per-100-g value that comes from your own food label or database lookup. Then type the portion weight and the number of servings you ate. The calculator returns total fat, calories from fat, and the percentage of your daily fat target. In Label mode, the process is reversed: enter the fat grams and serving size printed on a packaged product, and the tool standardizes the figure into fat per 100 g so you can compare it honestly with generic database values across different brands.
Formula Explained
All conversions in this tool come from a single straightforward proportion: fat content scales linearly with weight. If you know the fat value per 100 g, the fat in any portion is that value multiplied by the portion weight in grams and divided by 100. The same logic converts a label value to the per-100-g standard.
Fat in portion = (fat per 100 g ÷ 100) × portion weight × servingsLabel conversion = label fat ÷ label serving size × 100Calories from fat = total fat × 9 kcal/gShare of daily target = total fat ÷ daily target × 100%
Fat is the most energy-dense macronutrient, supplying 9 kcal per gram compared with 4 kcal per gram for protein and carbohydrate. The default daily target of 65 g corresponds to roughly 30% of calories from fat on a 2,000 kcal diet, which is the general reference value used on US Nutrition Facts labels. You can adjust the target field in the calculator to match your own dietary plan if your needs differ.
Reference Fat Values
The presets in the calculator come from USDA FoodData Central standard reference entries. Values are averages — actual products vary slightly by variety, ripeness, seed content, and processing method.
| Passion fruit form | Fat per 100 g | Notes |
|---|---|---|
| Fresh passion fruit (pulp & seeds) | 0.70 g | Fat comes almost entirely from the seeds |
| Passion fruit juice | 0.06 g | Pressed and filtered, nearly fat-free |
| Passion fruit nectar | 0.10 g | Added water and sweetener dilute all nutrients |

Worked Examples
Factors Affecting Accuracy
Whole fruit is variable by nature. Seed content dominates the fat in fresh passion fruit, so a fruit with many seeds will run higher than the 0.70 g reference, while a seedless variety runs lower. Ripeness, cultivar, and growing conditions all shift moisture and sugar content, which changes the fat concentration per 100 g. For packaged products, the most reliable number is always the one printed on the label of the exact product you are holding, because serving sizes, recipes, and added ingredients differ between brands.
Frequently Asked Questions
Is passion fruit really low in fat? Yes. Even the seeds, which contain the bulk of the fat, contribute well under 1 g per 100 g of whole fruit. Most of the energy in passion fruit comes from carbohydrates, mainly natural sugars and fiber.
Why do juice and nectar have even less fat? Because they are mostly water. Juice is pressed and filtered so most seed solids are removed, while nectar adds water and sweetener on top of the juice, diluting every nutrient further — including fat.
Why compare everything to 100 g? Nutrition labels in most countries and food databases worldwide use a per-100-gram (or per-100-millilitre) basis so that different products can be compared fairly regardless of serving size. A per-100-g figure removes the confusion of a company choosing a tiny serving size to make numbers look better.
