Cantaloupe is a popular summer melon valued for its sweet flavor, high water content, and light nutrient profile. Although it is not the first food people check for fat, knowing its fat content can still matter for precise meal tracking, low-fat diets, or macronutrient planning. This cantaloupe fat per 100g calculator estimates the total fat in any serving based on a standard value of 0.19 grams of fat per 100 grams of raw cantaloupe.
Use the calculator to convert a measured portion — grams, ounces, cups, or a typical half-cup serving — into total fat grams and the calories those fats contribute. You can also adjust the fat-per-100g value if you are using a different database or tracking a prepared dish with added fats. The result includes a daily value percentage based on a 78 g reference intake, which helps you see how little cantaloupe contributes to your overall fat allowance.
This tool is useful for dietitians, calorie counters, and anyone curious about the macronutrient profile of fruit. Cantaloupe is naturally very low in fat, so the numbers are small — but small values still add up when you are logging meals precisely.
🍈 Cantaloupe Fat per 100g Calculator
Estimate the total fat in any serving of cantaloupe, from a handful of cubes to a whole melon.
How to Use This Calculator
Start by entering the amount of cantaloupe you plan to eat. The calculator accepts grams, ounces, cups of cubed melon, half-cup pieces, or whole melons using an average weight of 552 grams for a medium melon. If you are weighing with a kitchen scale, choose grams or ounces. If you are following a recipe that lists fruit in cups, choose cups or half-cup pieces. Next, confirm the fat-per-100g value. The default of 0.19 g comes from the USDA nutrient database for raw cantaloupe, but you can edit it if your label or tracking app uses another value. Press Calculate to see the total fat, the amount in grams, the calories from fat, and the percentage of a 78 g daily fat reference.
The Calculation Method
The tool applies one simple formula: total fat = amount eaten in grams × (fat per 100 g ÷ 100). For example, if a serving weighs 200 g and the fruit contains 0.19 g fat per 100 g, the total fat is 200 × 0.0019 = 0.38 g.
Before multiplying, the calculator converts your chosen unit to grams with these factors: 1 oz = 28.3495 g, 1 cup of cubed cantaloupe = 177 g, ½ cup = 89 g, and 1 medium melon = 552 g. These conversions are based on typical US household measures for raw cantaloupe. Calories from fat are estimated by multiplying total fat grams by 9 kcal per gram, and the daily value percentage is calculated against a 78 g fat reference for a 2,000 kcal diet.
Because cantaloupe is mostly water and carbohydrates, the fat value is very small. The trace fat present is primarily polyunsaturated and monounsaturated fatty acids, with only a negligible amount of saturated fat.
Standard Values and Serving Sizes
Nutrition databases sometimes round cantaloupe fat to 0 g, but the measurable raw value is about 0.19 g per 100 g. The table below shows common portions and their approximate fat content using the default value.
| Portion | Weight | Total fat | Calories from fat |
|---|---|---|---|
| 100 g | 100 g | 0.19 g | 1.7 kcal |
| 1 oz | 28.35 g | 0.05 g | 0.5 kcal |
| ½ cup cubed | 89 g | 0.17 g | 1.5 kcal |
| 1 cup balls | 177 g | 0.34 g | 3.0 kcal |
| Whole melon | 552 g | 1.05 g | 9.4 kcal |
For reference, the FDA daily value for total fat is 78 g per day based on a 2,000 kcal eating pattern. A typical one-cup serving of cantaloupe provides less than 0.5% of that reference.
If you buy a pre-cut container, check the label or weigh the contents to confirm the actual amount. For a whole melon, the 552 g average assumes about 90% edible flesh after removing the rind and seeds; the exact edible yield can range from about 500 g to 600 g depending on size.
Worked Examples
Example 1: 150 g of cantaloupe. Convert to grams directly: 150 g. Then 150 × 0.0019 = 0.285 g fat. Calories from fat = 0.285 × 9 = 2.6 kcal. This is roughly 0.4% of the daily fat reference.
Example 2: 1.5 cups of cubed cantaloupe. One cup is 177 g, so 1.5 cups = 265.5 g. Total fat = 265.5 × 0.0019 = 0.50 g. Fat calories = 4.5 kcal.
Example 3: 6 oz of cantaloupe. Convert ounces to grams: 6 × 28.3495 = 170.1 g. Total fat = 170.1 × 0.0019 = 0.32 g.
Tips and Best Practices
Use a digital kitchen scale for the most accurate gram-based result. Cups are convenient but vary with cube size and how tightly the fruit is packed. If you are tracking a fruit salad or a smoothie, enter cantaloupe separately from the other ingredients rather than using a combined total. When a recipe adds butter, cream, or yogurt, those fats should be logged separately because they completely change the fat count.
If your nutrition app shows cantaloupe as 0.0 g fat, do not assume the number is wrong; many apps round values below 0.5 g to zero. The calculator keeps the decimals so that multi-ingredient totals remain meaningful.
Frequently Asked Questions
Is cantaloupe really fat-free? No food with measurable organic nutrients is completely fat-free, but cantaloupe is so low in fat that many labels round it to 0 g. The USDA value is about 0.19 g per 100 g of raw fruit.
Does the fat value change when cantaloupe is frozen or baked? Freezing does not remove fat. Baking or roasting without added oil keeps the fat almost unchanged per gram of fruit, though water loss can increase the fat density because the same fat is concentrated in less weight.
Where can I check the official nutrient data? The USDA FoodData Central database is the standard source for whole foods in the US. For daily value guidance, the FDA provides official nutrition labeling rules.
Can this value be used for meal planning? Yes. If your meal plan limits dietary fat, cantaloupe is a safe choice, but fats from dressings, seeds, or cheese sauces should be counted separately.
