In practice
Peanut butter is dense and sticky, so a cup weighs about 258 g on this page, though the type matters: natural peanut butter is oilier and runs, while commercial brands with added sugar and stabilisers are firmer. A measuring cup is awkward and messy, and the oil on the sides skews it, so spoon it onto a scale. Natural peanut butter may separate, so stir it well before measuring, otherwise the first spoonfuls are oily and the last are dry.
