Where 258 g comes from

USDA FoodData Central: 1 cup of “Peanut butter, smooth style, with salt (Includes foods for USDA's Food Distribution Program)” = 258 g. FDC 174266

King Arthur Baking ingredient weight chart (“Peanut butter”): 270 g per cup. Chart

This page uses 258 g (USDA). The two sources differ by 12 g (4.65%): that gap is about how firmly the cup is filled, not an error in either.

Peanut butter is dense: 258 g a cup in USDA's data; King Arthur's ½ cup at 135 g gives 270 g. Natural peanut butter that separates should be stirred first, or the top cup will be mostly oil.

How to measure peanut butter by the cup

Press it firmly into a dry measuring cup with the back of a spoon, then level the top. It should hold the cup's shape when turned out.
