Honeydew melon is refreshing, but when you are tracking protein it is easy to overlook how little protein a bowl of melon actually contains. This honeydew protein calculator converts any honeydew serving — grams, ounces, cups, tablespoons, or wedges — into grams of protein using USDA reference data. It also shows calories, carbohydrates, sugars, and the share of your daily protein target, so you get a complete macro snapshot in one click.
Use it to log an afternoon snack, check a fruit salad ingredient, or plan a high-protein meal that combines honeydew with Greek yogurt or cottage cheese. The quick-fill buttons handle common portions like 100 g and one cup, while the step-by-step breakdown explains exactly how each number is calculated. If you track macros daily, this tool makes a tiny nutrition fact easy to get right.

Step-by-Step Guide
This calculator is designed for quick macro checks. Start by entering the number of units in the Serving Amount field. Choose the unit from the dropdown — grams, ounces, cups of diced melon, cups of melon balls, tablespoons, or an approximate wedge. If you use one of the quick-fill buttons, the amount and unit are set for you and the calculation runs immediately.
Next, optional: update the daily protein target if you do not use the default 50 g. Leave the “Show full macros” box checked to see calories, carbohydrate, and sugar in the results. Press Calculate Protein. The result box shows total protein and the percentage of your daily target. If the input is missing or negative, you will see a clear error message.
The Math Behind the Calculator
Honeydew is mostly water and carbohydrate; USDA FoodData Central lists about 0.54 grams of protein per 100 grams of raw honeydew. All nutrient values in this calculator are scaled from that reference amount. The core formula is:
Protein = serving weight in grams × 0.54 ÷ 100
If you enter 1 cup of diced honeydew, the tool first converts the volume to grams using a density-equivalent value of 170 g per cup. It then multiplies by 0.54% to get 0.92 g. Energy, carbohydrates, and sugars are scaled the same way: 36 kcal, 9.09 g carbohydrate, and 8.12 g sugar per 100 g. Daily-value percentage is calculated with the equation protein ÷ target × 100. The step-by-step breakdown in the result area shows these three transformations clearly, so you can check the arithmetic by hand if you like.
Honeydew Protein Reference
The table below summarizes typical values using USDA nutrient data. Melon size and ripeness change moisture content, so treat these as practical approximations, not lab-exact numbers.
| Portion | Approx. weight | Protein | Calories |
|---|---|---|---|
| 100 g | 3.5 oz | 0.54 g | 36 kcal |
| 1 oz | 28 g | 0.15 g | 10 kcal |
| 1 cup diced | 170 g | 0.92 g | 61 kcal |
| 1 cup balls | 177 g | 0.96 g | 64 kcal |
| 1 tbsp diced | 11 g | 0.06 g | 4 kcal |
| 1 wedge | ≈125 g | 0.68 g | 45 kcal |
How Honeydew Fits in a High-Protein Meal Plan
Because honeydew is low in protein, it is best treated as a carb and fluid source rather than a protein source. A bowl of honeydew with 150 g of 2% Greek yogurt adds about 150 kcal but brings protein from roughly 0.8 g to 13–15 g. This kind of pairing makes fruit more satiating without changing the calculator’s numbers — it just adds another ingredient. To plan a full day of macros, use the serving values from this tool together with a Nutrition Target Calculator to see whether your meal fits your daily protein target.
For a side-by-side comparison, other fruit calculators on this site can help you find the highest-protein options in a fruit salad. For example, the Cherry Protein Calculator uses the same USDA-style approach, and comparing cherries with honeydew is a nice way to build a mixed bowl with a little more protein and fiber.
Frequently Asked Questions
Is honeydew a good source of protein? No. Honeydew contains about 0.5 g per 100 g, so it should not be used as a primary protein source. It contributes vitamins, potassium, and hydration but needs to be combined with protein-rich foods.
How many grams of protein are in a whole honeydew? A medium melon weighs roughly 1.3–1.8 kg, so protein could range from 7–10 g for the entire melon. Since edible flesh after rind removal is much lower, a realistic whole-fruit estimate is 5–8 g. This calculator uses portions, not whole-melon guesses, because melons vary so much.
Do ripeness and variety change the protein content? Slightly. The USDA value is an average for raw honeydew. Cooler storage and very ripe fruit lose water, which can make protein appear slightly higher per 100 g. The differences are usually under 0.1 g per serving, so they rarely matter for daily tracking.
Can I use cups if I do not have a kitchen scale? Yes. One standard measuring cup of diced honeydew is close to 170 g, but tightly packed pieces weigh more. If precision matters for structured meal prep, weigh the fruit and use grams for the most reliable numbers.
Limitations & Accuracy Notes
All calculations are based on the USDA FoodData Central entry for raw honeydew melon. Actual nutrient composition changes with variety, growing conditions, ripeness, and storage. Calories and macros are rounded to two decimals in the output. For strict medical or clinical purposes, consult a registered dietitian. Volume conversions like cups and wedges are practical estimates because diced pieces vary in size and packing density. You can browse the reference dataset directly at USDA FoodData Central. The default 50 g daily protein target is a generic benchmark; your personal requirement may be higher or lower depending on body weight, activity, and goals. Use the target field to match your own plan.
