  • These figures use the metric cup (250 ml). A US cup is slightly smaller at 240 ml, so it holds a little less. Use the US cup converter →
  • Cup sizes are not standard worldwide, so the same cup of an ingredient can weigh more or less depending on the country. What is a cup measurement →

Walnuts are used in baking, salads, cereals, and confectionery. One metric cup (250 ml) of walnut halves weighs around 106 grams or 3.74 ounces. When a recipe calls for walnuts by weight, you get the same amount every time regardless of how the halves happen to pack.

Walnut halves are bulky and leave air gaps in a measuring cup, so a cup measure can vary significantly depending on how the nuts settle. A gram weight removes that uncertainty.
