Walnuts — Grams & Cups Converter
1 cup of walnuts (also called chopped walnuts) weighs about 117 g, which makes a tablespoon 7.31 g and a teaspoon 2.44 g. Small amounts are easier to measure with spoons than to weigh.
💡 Tip: Walnut halves and chopped walnuts measure differently per cup. If a recipe says "1 cup walnuts," measure them whole, then chop.

Walnut halves vs chopped: why the cup differs
Walnut halves stack loosely, so a cup holds about 117 g, while chopped walnuts settle into the gaps and a cup weighs a little more. That's why a recipe's wording matters: 1 cup walnuts, then chopped, is less than 1 cup of already-chopped walnuts.
For the most reliable result, weigh them — and if a recipe just says 1 cup walnuts, measure them as halves and chop afterward.

Where walnuts sits by weight
117 g per cup places walnuts in the middle of its category — lighter than brazil nuts (130 g) and heavier than ground flaxseed (112 g).
Swapping these by the cupful is not like-for-like. A cup of brazil nuts in place of walnuts puts roughly 13 g more in the bowl, so match the grams rather than the cups.
