What a cup of chopped walnuts weighs, and why it can differ

USDA’s weight for “1 cup, chopped” is 117 g. Next to a cup of water, which holds about 236.6 g, that is 49% of the weight of a cup of water, so a lot of the cup is air. The same cup works out at 0.49 g per millilitre.

For a recipe that asks for 2 cups, that is a difference of 184 g between the lightest and the heaviest way to fill them, which is why the safest route is to weigh chopped walnuts instead.
