Metric cups and other cup sizes
The figures above use the US customary cup of 236.6 ml. A metric cup is 250 ml, so a metric cup of peanut butter weighs about 273 grams. UK recipes that say "cup" usually mean a 250 ml metric cup, which is why weighing in grams is more reliable than measuring by volume.
Measuring peanut butter accurately
Press peanut butter firmly into a dry measuring cup using a spatula to force out any trapped air pockets. Level the top completely flat before scraping it out. Natural peanut butter separates, requiring thorough stirring before measuring. Weighing peanut butter in grams bypasses these textural issues entirely.
