Frequently Asked Questions

About 1.10 cups, based on peanut butter having a density of 258g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 258 (grams per cup). For 10 ounces: 10 × 28.3495 = 283.50g, then 283.50 ÷ 258 = 1.10 cups.
For the most accurate results, weigh peanut butter on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 1.10 cups × 258g/cup = 283.50g, then 283.50g ÷ 28.3495 = 10 ounces. Or use the Cups to Ounces converter.
