Frequently Asked Questions
How many grams is a cup of peanut butter?
1 cup of smooth peanut butter, packed into the cup is 250 grams.
What should I know about measuring peanut butter?
This conversion is for smooth peanut butter, packed into the cup, and natural peanut butter (with oil separation) can weigh differently per cup than smooth commercial peanut butter, depending on how much oil has settled and been stirred back in.
Should I use a kitchen scale instead of cups?
For baking specifically, yes if precision matters — weight doesn't vary with how tightly an ingredient is packed, so it's more consistent than volume measurement. This converter helps translate a cup-based recipe to weight, or a weight-based recipe back to cups.
