How many calories are in watermelon?

Answer by  PZ (1206)

A cup of diced watermelon contains roughly 48 calories so it's a great choice if you're watching your weight. Watermelon is also rich in vitamin C, vitamin A and potassium. Snacking on watermelon is a good way to satisfy your craving for something sweet instead of making higher-calorie choices.

A small whole melon approximately 15 inches long and 7 inches wide has about 1355 calories, but if we are talking serving sizes it would be around 46 calories a cup.
