Formula and Step-by-Step

(pounds × 453.59g/lb) ÷ 258g/cup = cups
  1. Start with 0.5 pounds of peanut butter
  2. Convert pounds to grams: 0.5 × 453.59 = 226.80g
  3. 1 cup of peanut butter = 258g

First convert pounds to grams (1 pound = 453.592g), then divide by 258 (grams per cup). For 0.5 pounds: 0.5 × 453.592 = 226.80g, then 226.80 ÷ 258 = 0.88 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.
