How to measure 1/8 cup of peanut butter

By weight (most accurate): set your bowl on a kitchen scale, press tare, and add 32 g of peanut butter.

By volume: Use 2 level tablespoons. Most measuring-cup sets do not include a 1/8 cup.

Peanut butter is dense and sticky. Weighing it directly into the bowl is faster than scraping out a measuring cup.

Why peanut butter weighs what it does

Peanut butter is about 9% heavier than the same volume of water, which weighs about 237 g per cup. That is why you can't convert cups to grams without knowing the ingredient.
