Peanuts are used in baking, confectionery, trail mixes, and savoury dishes across many cuisines. One metric cup (250 ml) of raw whole peanuts weighs around 154 grams or 5.43 ounces. When a recipe calls for peanuts by weight, you avoid the packing variation that comes with a cup measure.

Whole peanuts settle and pack differently depending on their size and how the cup is filled, so a loosely poured cup can weigh notably less than a firmly packed one. A gram weight removes that variable.
