Frequently asked questions

How many grams is 1 cup of peanut butter?

1 US cup of peanut butter weighs 258 g, as measured by the USDA (1 cup (smooth)). A tablespoon weighs 16.1 g.

How do I convert grams of peanut butter to cups?

Divide the grams by 258. For example, 100 g of peanut butter is 0.39 cups, about 1/3 cup + 1 tbsp.

Is a US cup the same as a metric cup?

No. A US cup is 236.6 ml and a metric cup (Australia, Canada, New Zealand) is 250 ml, so a metric cup of an ingredient weighs about 5–6% more than the US weights here.

Why weigh instead of using cups?

How you fill a cup changes how much goes in: scooped flour packs down, spooned flour stays loose. Weighing gives the same amount every time, which matters most for baking.
