Here are some quick conversions that may help you decode your recipe:

2 cups: 1 pint
1 cup: 6 ounces

But what if you buy your blueberries by the pound? Well, according to HowMuchIsIn.com, one 1-pound carton of fresh blueberries contains about 3 to 3½ cups of fruit. A 1-quart carton, meanwhile, will have about 4 ½ cups of blueberries.

If you’re an absolute sadist, you technically could count your blueberries one-by-one. One cup is equal to about 65 to 75 normal-sized fresh blueberries. But, since all blueberries are not created equal, just use a measuring cup for accurate results.

If your recipe uses the metric system, one cup of blueberries weighs about 190 grams.
