peanut butter grams to cups Converter

How the peanut butter conversion works

The converter applies cups = grams ÷ grams-per-cup. A US cup is 236.588 ml, and peanut butter's weight per cup is about 258 g smooth or about 250 g crunchy — the trapped air in crunchy costs a few grams per cup.

Worked example: a recipe calling for 100 g of smooth peanut butter needs 100 ÷ 258 ≈ 0.39 cups. A tablespoon is about 16 g, so 100 g is roughly 6 tablespoons.

Treat every preset as typical, not exact: style, brand and oil separation all shift the weight. When a bake has to be right, weigh with a scale — and lightly oil the cup first, so the sticky stuff slides off instead of clinging.
