Pecans:
Grams to Cups
By Stefan Ulrich · Last updated
Pecan halves weigh just 109 grams per cup — among the lightest nuts per cup due to their large, curved shape that creates significant air space. Chopped pecans pack more densely at approximately 120 g/cup.

About Pecans
Pecans' distinctive crescent shape means they stack with large gaps between pieces, resulting in a remarkably low weight per cup. This makes pecans particularly unreliable when measured by volume — a firmly pressed cup of pecan halves can weigh 15–20% more than one loosely filled.
For pecan pie, most classic recipes call for 1 to 1½ cups of pecan halves. At 109 g/cup, that's 109–164 g. If you weigh your pecans, you'll get a more consistent pie every time — and you can arrange them in the filling for a more photogenic result.
Toasted pecans are transformatively better than raw in almost every application. Toast at 350°F (175°C) for 8–10 minutes, shaking the pan halfway through. The sugars in pecans caramelize at a lower temperature than many other nuts, so they benefit from careful watching.
Ground pecans (pecan meal) weigh approximately 95–100 g/cup. They can be used as a partial flour substitute in shortbread, tart crusts, and butter cookies — typically replacing 25–30% of the all-purpose flour for a sandy, nutty texture.
Tips for measuring Pecans
- Halves: ~109 g/cup. Chopped: ~120 g/cup. Ground: ~100 g/cup.
- Toast at 350°F/175°C for 8–10 min — pecans burn faster than most nuts.
- Store in the freezer — high fat content means rapid rancidity at room temp.
- For pecan pie, weigh pecans for consistent results batch to batch.
Common mistakes
- Pressing pecan halves into the cup — 15–20% overmeasurement vs. loosely filled
- Over-toasting — pecans go from golden to burned quickly due to high sugar content
