A pint of blueberries weighs around three-quarters of a pound, or 12 ounces. 1 pound contains 16 ounces, which equates to 1 1/3 quarts of blueberries.
A dry pint is a volume measurement, not a weight measurement, hence a pint of one substance does not weigh the same as a pint of another substance. A pint of blueberries equals roughly two cups of dry measure. The weight of pints of blueberries sold in supermarkets might vary. A 10-ounce container of frozen blueberries contains just around 1 1/2 cups. My Recipes’ Marge Perry recommends letting frozen blueberries defrost before incorporating them into a meal, as this preserves their texture.
