Pecans:
grams to cups.
Chopped pecans weigh about 99 g per cup — lighter than walnuts per cup because pecan pieces are more irregular in shape and pack with more air gaps. The hollow, ridged structure of pecan halves means even a firmly filled cup holds less mass than you might expect.

Pecan halves vs chopped: two very different cup weights
Pecan halves packed into a cup weigh significantly less than chopped pecans — roughly 85–90 g versus 99 g for a medium chop. The long, curved half-shells stack haphazardly and leave large air pockets. When a recipe calls for "1 cup pecans," it typically means roughly chopped pieces unless "halves" is specified. Using whole halves in a recipe that calls for chopped will give you fewer pecans by weight, which matters in pralines, pecan pie, or any recipe where the pecan-to-sugar ratio is important. When in doubt, chop to a medium size and weigh 99 g.
Pecans in pralines and pies: where exact quantity shifts the texture
Classic pecan pie filling is a custard made with eggs, corn syrup or sugar, and butter — the pecans sit on top and partially sink in. The quantity of pecans determines the nut-to-filling ratio and affects how the pie slices. Too few pecans produces a filling-heavy, soft slice; too many creates a dry, nut-dominated texture. Pecan pralines are even more sensitive: the exact ratio of sugar syrup to pecans determines whether the praline sets to a creamy candy or a brittle one. In both cases, weighing pecans (99 g per cup) gives you the consistent ratios these recipes were developed with.
