| Serving | Weight | State | Kcal | Protein | Fat | Carbs |
|---|---|---|---|---|---|---|
| 1 watermelon wedge without rind | 286 g | Raw, edible flesh | 85.8 | 1.74 g | 0.43 g | 21.59 g |
| 1 cup diced watermelon | 152 g | Raw, edible flesh | 45.6 | 0.93 g | 0.23 g | 11.48 g |

What affects the calorie value
The calculation covers edible flesh without rind. Watermelon contains a high proportion of water, so calories per 100 g are low, but a large serving depends on its total weight.
Juice, smoothies and sweetened watermelon drinks cannot automatically use the whole-flesh record. Changed composition and added sugar require a recipe calculation or package label.
Vitamins and minerals per 100 g
Values come from the same USDA records. They show the amount in the food, not a percentage of an individual daily requirement.
| Nutrient | Raw, edible flesh |
|---|---|
| Vitamin C, mg | 8.1 |
| Potassium, mg | 112 |
| Vitamin A, RAE, µg | 28 |
| Magnesium, mg | 10 |
| Vitamin B6, mg | 0.05 |
| Manganese, mg | 0.04 |
How to calculate more accurately
Slice size alone does not determine calories. Remove the rind and weigh the flesh you will eat.
For a bowl, use the combined flesh weight. The 250 g shortcut is a serving example, not dietary advice.
Count juice and sweetened drinks separately; their composition is not the same as whole watermelon flesh.
