This cantaloupe nutrition calculator gives you a complete breakdown of the calories, macronutrients, and key micronutrients in fresh cantaloupe (also known as muskmelon or rockmelon). Whether you're tracking calories, counting carbs, or boosting your vitamin A and C intake, this tool helps you quickly estimate the nutritional value of any portion you plan to eat.
Simply enter the amount of cantaloupe you're eating, choose your preferred unit (grams, ounces, cups of diced fruit, or whole melon), and the calculator will instantly show calories, protein, carbohydrates, fiber, sugar, fat, potassium, vitamin A, and vitamin C. You can also adjust for the edible portion if you're weighing the whole fruit with rind and seeds.
This tool is ideal for meal planning, diet tracking, and anyone curious about the health benefits of this refreshing summer fruit. It's also handy for comparing cantaloupe to other fruits in your daily nutrition goals.

How to Use This Tool
Using the cantaloupe nutrition calculator is straightforward. Start by entering the amount of cantaloupe you plan to eat in the input field. You can choose from four units: grams, ounces, cups of diced fruit, or whole melons. If you're measuring with a kitchen scale, grams or ounces are most accurate. If you're following a recipe that calls for diced cantaloupe, the cup option is convenient. For a quick estimate based on a whole fruit, select the whole melon option.
The calculator also includes a checkbox labeled "Adjust for edible portion." This is important if you weigh the entire melon including the rind and seeds. Cantaloupe's edible flesh makes up only about 51% of the whole fruit's weight. When this option is checked, the calculator automatically multiplies your entered weight by 0.51 to estimate the actual flesh you'll eat. If you're entering the weight of just the flesh (after removing rind and seeds), leave this unchecked for the most accurate result.
After clicking "Calculate Nutrition," you'll see a detailed breakdown of calories, protein, carbohydrates, fiber, sugar, fat, potassium, vitamin A, and vitamin C. The step-by-step breakdown below the results explains how the numbers were derived, so you can verify the math and understand the conversion factors used.
How It Works
The calculator uses standard USDA FoodData Central values for raw cantaloupe. Per 100 grams of edible flesh, cantaloupe contains approximately:
- Calories: 34 kcal
- Protein: 0.84 g
- Carbohydrates: 8.16 g
- Fiber: 0.9 g
- Sugar: 7.86 g
- Fat: 0.19 g
- Potassium: 267 mg
- Vitamin A (RAE): 169 mcg
- Vitamin C: 36.7 mg
To calculate your portion, the tool first converts your input to grams. The conversion factors are: 1 ounce = 28.3495 grams, 1 cup of diced cantaloupe = 156 grams, and 1 whole melon = 552 grams (edible flesh weight). If the edible portion adjustment is enabled, the total grams are multiplied by 0.51 to account for the rind and seeds. Then, each nutrient value is scaled proportionally by dividing the grams by 100 and multiplying by the per-100g value.
For example, if you enter 200 grams of cantaloupe flesh, the calculator multiplies each per-100g value by 2.0. You'd get 68 calories, 1.68 g protein, 16.32 g carbs, 1.8 g fiber, 15.72 g sugar, 0.38 g fat, 534 mg potassium, 338 mcg vitamin A, and 73.4 mg vitamin C.
Worked Examples
Example 1: Snack portion
You want to eat 1 cup of diced cantaloupe. The calculator converts 1 cup to 156 grams. With the edible portion checkbox unchecked (since you're measuring the flesh directly), the results are:
Calories: 53 kcal, Protein: 1.31 g, Carbs: 12.73 g, Fiber: 1.40 g, Sugar: 12.26 g, Fat: 0.30 g, Potassium: 416 mg, Vitamin A: 264 mcg RAE, Vitamin C: 57.3 mg.
Example 2: Whole melon with rind
You buy a whole cantaloupe that weighs 1.5 kg (1500 g) including rind. You check the edible portion box. The calculator multiplies 1500 g by 0.51 to get 765 g of edible flesh. Then it scales the per-100g values by 7.65. You'd get approximately 260 kcal, 6.43 g protein, 62.4 g carbs, 6.89 g fiber, 60.1 g sugar, 1.45 g fat, 2043 mg potassium, 1293 mcg vitamin A, and 281 mg vitamin C.
Tips & Best Practices
- Use a kitchen scale for accuracy. Volume measurements like cups can vary depending on how finely you dice the fruit. Weighing in grams gives the most reliable nutrient estimates.
- Remember the edible portion factor. If you're tracking calories strictly, always weigh the flesh only, or use the edible portion adjustment when weighing the whole fruit.
- Consider ripeness. Sugar content can vary slightly with ripeness. A very ripe cantaloupe may have a bit more sugar, but the differences are small and unlikely to affect your daily totals significantly.
- Pair with other foods. Cantaloupe is low in protein and fat, so it's often paired with yogurt, cottage cheese, or nuts for a more balanced snack. Use this calculator alongside other nutrition tools to plan complete meals.
Factors Affecting Accuracy
The nutrient values used here are averages from the USDA FoodData Central database. Actual values can vary due to growing conditions, variety, ripeness, and storage. The edible portion factor of 51% is also an average; some melons may have thicker rinds or more seeds, changing the ratio slightly. For clinical or medical purposes, always consult a registered dietitian or use laboratory analysis if precise values are required.
Additionally, the cup-to-gram conversion assumes standard diced pieces. If you cut larger chunks, a cup may weigh slightly more or less. The whole melon weight of 552 grams is based on a medium-sized cantaloupe; larger or smaller fruits will differ. When in doubt, weigh your specific portion.
Frequently Asked Questions
Is cantaloupe good for weight loss?
Cantaloupe is low in calories (about 34 kcal per 100 g) and high in water content, making it a filling, hydrating snack. Its natural sweetness can help satisfy sugar cravings without excessive calories. However, portion control still matters, as eating a whole melon adds up to about 190 calories.
How much vitamin C is in a serving of cantaloupe?
A 100-gram serving provides about 36.7 mg of vitamin C, which is roughly 41% of the Daily Value (90 mg for adults). One cup of diced cantaloupe (156 g) provides about 57 mg, covering over 60% of your daily needs.
Is cantaloupe high in sugar?
Cantaloupe contains about 7.86 g of sugar per 100 g. This is moderate compared to some tropical fruits like mango or grapes. The sugar is naturally occurring and comes with fiber, water, and micronutrients, making it a healthier choice than processed sweets.
Can I use this calculator for frozen or dried cantaloupe?
No, this calculator is designed for fresh raw cantaloupe. Frozen and dried forms have different water content and nutrient density. Dried cantaloupe, for example, is much higher in calories and sugar per gram. For those products, look for specific nutrition labels.
