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

USDA’s weight for “1 cup, chopped” is 109 g. Next to a cup of water, which holds about 236.6 g, that is 46% of the weight of a cup of water, so a lot of the cup is air. The same cup works out at 0.46 g per millilitre.

Depending on how it is prepared, a cup of chopped pecans ranges from 99 g (halves) to 109 g (chopped) in USDA’s own entry: 10 g apart, and the heavier cup holds 1.10 times the lighter.

For a recipe that asks for 2 cups, that is a difference of 20 g between the lightest and the heaviest way to fill them, which is why the safest route is to weigh chopped pecans instead.
