Blueberries: Grams to Cups
1 cup of blueberries = 148 grams
One US cup of blueberries weighs 148 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 156 grams. To convert any weight, divide the grams by the figure for your cup.
A cup of fresh blueberries weighs 148 g, the household measure USDA FoodData Central records for raw blueberries. Whole berries are firm and round, so they do not compress the way flour or leaves do — fill the cup and level it by hand. 100 g is about ⅔ cup (0.68 cup).
