Interesting fact: Blueberries are so light that nutrition labels usually measure them by cup rather than by berry.
The answer: Typically, a blueberry weighs about 1 to 2 grams (0.04 to 0.07 ounces). The exact weight depends on size, variety, preparation, brand, and how much edible or non-edible material is included.
Fruit weights change with ripeness, seed size, water content, and variety. Knowing a typical range is useful for recipes, lunch packing, calorie estimates, grocery planning, and understanding why one piece can feel much heavier than another.
