Close, but not exactly. The ounces to cups conversion for peanut butter may vary slightly between brands depending on moisture content and how the ingredient is measured.
The same weight of different ingredients fills different volumes because each ingredient has a different density. An ounce of peanut butter fills a different number of cups than an ounce of a lighter or heavier ingredient. That is why this converter needs to know which ingredient you are measuring.
