Question: how many grams is 1 serving of watermelon?
Answer: If you dice it, a single serving is 1 cup of cubed melon. When using a melon baller to cut the watermelon, a single serving is about six balls of melon. A small 1-inch thick wedge of sliced melon is also equivalent to one serving. Adult men and women need to eat 1 1/2 to 2 cups of fruit each day.
