One US cup of watermelon (diced) weighs 152 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 161 grams. To convert any weight, divide the grams by the figure for your cup.
A cup of diced watermelon weighs 152 g (USDA FoodData Central, watermelon, raw). Melon balls pack almost the same, 154 g a cup. USDA weighs a wedge of about 1/16 of a melon at 286 g, a little under 2 cups once it is cut from the rind. Watermelon is over 90% water, so a cup weighs about two thirds of a cup of water.
