Whole Shelled Hazelnuts: US Cups to Grams (g) & Ounces (oz) Conversion
Convert volumes of whole, shelled hazelnuts (also known as filberts) measured in US cups to their approximate weight in metric grams (g) and imperial/US ounces (oz).

Important Considerations for Whole Hazelnuts:
Whole, shelled hazelnuts are relatively dense. A common average is around **140-150 grams per US cup** (approximately 5 ounces).
This chart assumes shelled hazelnuts. Hazelnuts in their shells will weigh significantly more per cup overall, but the kernel weight will be less.
Chopped hazelnuts will pack differently and may have a slightly different weight per cup (usually a bit heavier).
For recipes where the quantity of hazelnuts is important, such as in certain cakes, cookies, or confections, measuring by weight provides greater accuracy.
