Peanut butter: cup, tablespoon and jar sizes
Peanut butter is thick and traps air, so press it firmly into the cup and level the top — a properly packed cup is about 258g (9 oz). A tablespoon is roughly 16g, and the familiar 2-tablespoon serving on the label is about 32g.
Working from a jar instead of a recipe? A 16 oz (454g) jar holds about 1¾ cups, a 12 oz jar about 1⅓ cups, and a big 28 oz jar about 3 cups. Natural and no-stir styles weigh about the same once stirred smooth.
