Walnut Halves: US Cups to Grams (g) & Ounces (oz) Conversion
Convert volumes of walnut halves measured in US cups to their approximate weight in metric grams (g) and imperial/US ounces (oz). Walnut pieces fill a cup differently than chopped nuts.

Important Considerations for Walnut Halves:
The weight of walnut halves per cup can vary based on the size of the halves and how they pack into the cup. A common average is around **100-115 grams per US cup** (approximately 3.5-4 ounces).
Chopped walnuts will generally weigh more per cup as smaller pieces pack more densely.
For recipes where the amount of nuts is critical for texture or flavor balance, measuring by weight with a kitchen scale is recommended for better consistency.
