A pint of blueberries weighs about three-quarters of a pound, or 12 ounces. 1 pound contains 16 ounces, which equates to 1 1/3 pints of blueberries.
A dry pint is a volume measurement, not a weight measurement, so a pint of one material does not weigh the same as a pint of another material. A pint of blueberries equals approximately two dry cup measures. The weight of pints of blueberries sold by stores can vary. A 10-ounce package of frozen blueberries is only equivalent to about 1-1/2 cups. My Recipes’ Marge Perry recommends thawing frozen blueberries before adding them to a dish in order to preserve their texture.
