Blueberries weigh a different amount depending on how many of them there are, although a pint of blueberries weighs around one pound. A pint of blueberries can be converted into Â¾ pound or 2 cups. 1 quart of blueberries can be converted into 1-1/2 pounds or 4 cups. A single 10-ounch package of frozen blueberries can be converted into 1-1/2 cups. A gallon of blueberries weighs about 6 pounds or 8 ounces, although they are rarely sold in this large of a size.
Often times grocery stores will put blueberries into smaller containers, though they are sometimes put into larger bags which tend to be much more costly for the consumer.
