Visualizing 100 Grams of Watermelon

To truly grasp what a 100-gram serving looks like, it's easiest to translate it into common kitchen measurements and visual references. A 100g portion is approximately two-thirds of a cup of diced watermelon. For a whole melon, this is a very small wedge. If you're cutting from a large watermelon, it's often a single, modest slice. Think of a small handful of cubes or a slice roughly the size of a standard smartphone screen. Because watermelon is so dense with water, its volume-to-weight ratio is a key factor in understanding portion size.

Practical Visuals for Portion Control

  • Diced cubes: Roughly 10-15 one-inch cubes, depending on the exact size and water content.
  • Small spheres: A small handful of watermelon balls, scooped with a melon baller.
  • Small wedge: A thin slice from a small to medium watermelon, about 1/16th of the melon.
