How to measure blueberries
The USDA entry is “Blueberries, raw, 1 cup = 148 g”. King Arthur Baking’s chart lists fresh or frozen blueberries as a range, 140 to 170 grams per cup, and frozen mixed berries at 142 grams, so 148 grams lands near the low end of that range. The chart gives a range rather than one number, so the cup weight of blueberries is less fixed than most. Half a cup is 74 grams and a quarter cup 37 grams. A cup of dried blueberries is heavier at 156 grams on the King Arthur chart, so do not swap fresh and dried by the cup.
Sources: 148 grams per US cup is the cup weight in USDA FoodData Central (open FDC entry 171711), entry “Blueberries, raw, 1 cup = 148 g”. A US cup is about 237 milliliters.
