Honeydew melon is a mild, refreshing fruit that quietly contributes meaningful vitamin C to your diet — about 18 mg per 100 g of flesh, which is 20% of the daily value. Yet most people have no idea how much they're actually eating when they scoop out a half-cup or slice a wedge. This Honeydew Vitamin C Calculator turns your portion into a precise milligram number, whether you measure by grams, ounces, cups of diced fruit, melon balls, or even fractions of a whole melon.
Designed for meal planners, nutrition students, athletes, and anyone keeping an eye on micronutrients, the tool also shows what that amount means as a percentage of your daily vitamin C target. Adjust the daily value if your goal differs from the standard 90 mg reference. Quick preset buttons make common portions one click, and a step-by-step breakdown shows exactly how the number was calculated. Just enter your portion, hit Calculate, and see your honeydew's vitamin C contribution in seconds.
🧺 Honeydew Vitamin C Calculator
Enter how much honeydew you're eating — by weight, cup, or whole melon — to get its vitamin C content in milligrams and the percentage of your daily value.
Why Honeydew Is a Smart Vitamin C Choice
Honeydew melon is often overlooked next to oranges and strawberries, but a generous bowl of sliced honeydew is a genuinely useful source of vitamin C. A 100 g portion (roughly two-thirds of a cup of diced fruit) supplies about 18 mg of vitamin C, which is 20% of the FDA's 90 mg Daily Value used on nutrition labels. Because honeydew is mostly water and natural sugar, it is a light and hydrating way to push your daily intake higher, especially in warm months.
This calculator is designed for anyone tracking micronutrients: meal planners building balanced menus, athletes checking post-workout fruit portions, dietitians estimating client intakes, and parents wondering whether the fruit bowl is contributing enough vitamin C for the day.
How the Calculation Works
The tool uses the USDA nutrient value for raw honeydew melon: 18 mg of vitamin C per 100 g of edible flesh. That is equivalent to 0.18 mg per gram or about 5.1 mg per ounce. The calculator first converts your selected unit into grams, then multiplies that weight by 0.18.
Portion conversions used in the calculator are based on standard USDA cup measurements and typical edible yields:
- 1 cup diced honeydew ≈ 170 g
- 1 cup honeydew balls (1-inch pieces) ≈ 177 g
- 1 medium honeydew melon ≈ 800 g of edible flesh after removing rind and seeds
The Daily Value percentage is then calculated against the FDA reference amount of 90 mg vitamin C per day. You can adjust the daily value field in the calculator to match a different personal target, such as the RDA for adult women (75 mg), men (90 mg), or pregnancy (85 mg).
Worked Examples
Example 1: One cup of diced honeydew. Select cups diced and enter 1. The calculator converts to 170 g, then computes 170 × 0.18 = 30.6 mg. That is 34% of the standard 90 mg Daily Value, a meaningful contribution to your vitamin C quota.
Example 2: A 200 g breakfast bowl. Weigh out 200 g of honeydew chunks on a food scale. Vitamin C = 200 × 0.18 = 36 mg, or 40% of the Daily Value. Add half a grapefruit or a handful of strawberries and you have covered most of the day's need without a supplement.
Example 3: Half a medium melon. Half a melon is about 400 g of flesh. The calculation gives 400 × 0.18 = 72 mg, which is 80% of the 90 mg Daily Value.
Reference Table: Honeydew Vitamin C by Portion
| Portion | Weight (g) | Vitamin C (mg) | % DV (90 mg) |
|---|---|---|---|
| 100 g | 100 | 18.0 | 20% |
| 1 oz | 28.3 | 5.1 | 6% |
| 1 cup diced | 170 | 30.6 | 34% |
| 1 cup balls | 177 | 31.9 | 35% |
| ½ medium melon | 400 | 72.0 | 80% |
| 1 medium melon | 800 | 144.0 | 160% |
Values are approximations and vary with cultivar, ripeness, and growing conditions. The 18 mg per 100 g figure is from the USDA FoodData Central nutrient database.
Tips for Accurate Tracking
Weighing honeydew in grams on a kitchen scale gives the most reliable result. Cup measures can vary depending on how tightly you pack diced pieces, and whole melons range from about 500 g to over 1 kg of edible flesh. When using the medium melon option, picture a melon about 6 to 7 inches across, yielding roughly 4 cups of diced fruit.
- Eat honeydew raw to preserve its vitamin C. Prolonged heat can degrade vitamin C, and cooking melon is unusual anyway.
- Freshly cut fruit loses vitamin C over time through oxidation. Store cut honeydew in a sealed container in the fridge and eat it within two to three days.
- Pair honeydew with iron-rich foods such as lentils, spinach, or beans. The vitamin C in honeydew helps the body absorb non-heme iron more efficiently.
- If you are counting carbohydrates, remember honeydew contains about 8 g of sugar per 100 g. The vitamin C is valuable, but portion still matters for blood-sugar management.
If you track vitamin C across several foods, you can also run the cucumber vitamin C calculator or bagel vitamin C calculator to compare different items in your daily totals.
Frequently Asked Questions
Is honeydew high in vitamin C? It is moderate. At about 18 mg per 100 g, honeydew contains less vitamin C than oranges, kiwifruit, or strawberries, but more than apples, pears, and bananas. It is similar to mango and cantaloupe, making it a useful everyday source rather than a concentrated one.
Should I use 90 mg or another Daily Value? The FDA uses 90 mg on Nutrition Facts labels, while the National Institutes of Health lists an RDA of 75 mg for adult women and 90 mg for adult men. Pregnant and lactating women need 85 mg and 120 mg respectively. Use the calculator's daily value field to match your personal target.
Does honeydew provide other nutrients? Yes. It also supplies potassium, folate, vitamin B6, and magnesium, and it is about 90% water, which supports hydration without adding fat or cholesterol.
Can eating too much honeydew be a problem? For most healthy people, a cup or two a day is a perfectly reasonable low-fat snack. Honeydew contains natural sugar, so people with diabetes should fit the carbohydrate into their meal plan. Some people with IBS may find honeydew triggers bloating due to its FODMAP content.
